Note: If you are copying amplicons into a pre-existing design, amplicons mustbe of the same genome, or in draft form only.

5. After you compile a list of targets for which you want to create a new design,click Submit targets, then confirm your submission. See “Start a new DNA Genedesign“ on page 26 for further information on how to submit Made-to-Orderdesigns.

Note: Subset designs can be combinations of predesigned regions andamplicons from custom designs mixed and matched with amplicons from othercustom designs or Ready-to-Use and Community Panels.

• Custom amplicons from a private design that is shared with you by a colleaguecannot be copied using the "Add Amplicon By ID" form or the "Upload File"method. Amplicons can only be copied using the Copy Amplicons button anddialogs in the UI.

• The following DNA panels are not compatible for use with the Copy Ampliconsfunction:

– HID - Precision ID Identity Panel (Cat. No. A25643)– HID - Precision ID Ancestry Panel (Cat. No. A25642)– Ion AmpliSeq™ Exome RDY Panel– Ion AmpliSeq™ Colon and Lung Cancer Panel

• RNA panels are also not compatible for use with the Copy Amplicons function,because RNA designs are based on predesigned primers for every transcript inour database. For RNA designs, use the Copy Targets function to create Made-to-Order RNA designs containing the same amplicons.

• Amplicons that are greater than 200 bp in size cannot be copied to Ion AmpliSeq™

HD designs.

Basic and biological filtering

The human genome is heavily populated with repeat regions that make designingprimers difficult, a well known challenge in PCR design. The Ion AmpliSeq™ Designerpipeline has been developed to deliver the most robust set of amplicons it cangenerate. The pipeline specifically excludes amplicons that are placed in repeatelements or other hypervariable regions to generate the best possible outcome foractual amplicon coverage when used in a reaction.

A focus in our Research & Development department is to better understand theproperties of repeat regions to allow primer placement in these regions to achievehigher target design rate while maintaining coverage uniformity and on-target rates.

The biological filtering mechanism that is incorporated into the Ion AmpliSeq™

Designer pipeline to evaluate repeat elements is the RepeatMasker. RepeatMasker is aprogram that screens DNA sequences for interspersed repeats and low complexityDNA sequences, and is an annotation track that is available through the UCSCGenome Browser. Ion AmpliSeq™ Designer links directly to the browser and offers theuser the visual representation to distinguish between three BED files as customannotation tracks.

• Resulting BED file for the design that was submitted (the data appears under the"InputTargets" blue label in the UCSC browser)

• Resulting BED file for the design that is generated by the application (the dataappears under the "CoveredBases" green label in the UCSC browser)

• The difference between these two BED files (the data appears under the"MissedBases" red label in the UCSC browser)

While G-C bonds contribute more to the stability, and therefore increased meltingtemperature, of primer/template binding than do A−T bonds, it is important to notethat two primer/template complexes with similar or even identical GC content canresult in a different melting temperature because of base order influence on overallstability.

GC-rich regions for the target DNA are difficult to amplify, and are generally avoidedwhen defining an in silico algorithm.

When submitted as a manual target region with coordinates:chr13:48877883-49056026, the resulting coverage was 38.31% with 4 pools and 611amplicons.

In closer examination of the design results, it is apparent that the majority of thisregion is interspersed with repeat elements.

An attempt to re-design the region by input type Gene + UTR results in coverage of92.58% with 4 pools and 60 amplicons.

Start a new Ion AmpliSeq™ On‑Demand Panel design

Ion AmpliSeq™ On-Demand Panels represent an alternative way to design panels foruse in inherited disease (germline mutation) research applications. Ion AmpliSeq™

On-Demand Panels can be designed by selecting genes using a content selectionengine, or uploading your own gene list. Each panel consists of two DNA primerpools, and the number of primer pairs per pool depends on the genes you select.Presently, Ion AmpliSeq™ On-Demand Panels are limited to 500 genes and/or 15,000amplicons. The gene designs in the On-Demand catalog have been optimized for highperformance. You can add genes that are not in the On-Demand catalog to your panelas a Spike-in Panel.

This section covers how to design an Ion AmpliSeq™ On-Demand Panel using thefeatures and tools available in Ion AmpliSeq™ Designer.

Reference FASTA sequence

Uploading sequences

One or more reference sequences in FASTA format can be uploaded by:

a. Selecting a "plain text" or compressed file (in either ZIP or GZIP formats) containingthe sequence(s). The maximum file size allowed for upload is 1 GB afterdecompression.

b. Copying and pasting the sequences in the text area available after clicking on thelink "Enter FASTA data in a text area instead."

FASTA format

A sequence in FASTA format is expressed in 2 or more lines of text: The first line is anidentifying "header", the rest of the lines (one or more) represent the sequence itself.

• The header: The header line starts with a "greater-than" symbol (">") followed byat most 64 ASCII characters. Allowed characters are A-Z, a-z, 0-9, "_" and "-", withNO SPACES between them. Since the header is used to identify the sequence, it isrequired to be unique for each sequence in the reference.

• The sequence: The only characters accepted for representing a sequence are "A,""C," "G," "T," and "N" (lower case versions are also allowed for representing lowcomplexity regions). Although a sequence can be just one or multiple lines ofdifferent size after the header, it is traditional to use separate lines of 50 or 60characters in length.

• Sequence size: The minimum length of a sequence is 160 bp: allowing 60 bp forminimum insert size, plus 50 bp upstream and 50 bp downstream to serve as adesign buffer for primer positioning during amplicon design; however, therecommended upstream and downstream context buffer sequence for optimaldesigns is 1,000 bp.

Known polymorphism BED file

The known polymorphism BED file indicates regions of the sequences in the customreference FASTA file with high polymorphism (for example, SNPs, indels, or othervariations). Ion AmpliSeq™ Designer minimizes primer overlap with these regions.This file is . You can upload it at the time of creating a new custom reference.

The BED format is a tab-delimited file, with one line per region. Required fields arechrom, chromStart, and chromEnd in the first three columns of the BED file format.Additional fields are ignored.

The chrom field must match one contig ID in the accompanying FASTA file.chromStart and chromEnd fields are the zero-based, half-open coordinates indicatingthe region to target in the sequence identified by the ID in the chrom field. chromStartand chromEnd are relative to the sequence of the FASTA record corresponding to thegiven ID.

Appendix B Supplemental informationReference FASTA sequenceB


The chrom, chromStart, and chromEnd fields must meet the following criteria:• chromStart can be a value between 0 and length of the sequence specified by

chrom−1.• chromEnd must be greater than chromStart.• chromEnd can have a maximum value of the length of the sequence specified by

chrom.• No region should overlap any other region in the file. Combine overlapping

regions into a single contiguous region.• The variant coordinates BED file must have no header (for example, no "track"

lines).

Pipeline details

When you use Ion AmpliSeq™ Designer, the tiling and pooling algorithms run behindthe scenes to transform your submitted design into an orderable Custom IonAmpliSeq™ kit.

The following sections describe the Ion AmpliSeq™ tiling and pooling processes.

Appendix B Supplemental informationPipeline details B


The pipeline is optimized to find the highest coverage with the least number ofamplicon pools. In an attempt to design all primer pairs exhaustively, the pipelinecreates an exhaustive search by sliding a tiling window one-base at a time across theentire targeted region.

Start End

In creating the primers, the pipeline considers:• A basic filtering

– Optimal melting temperatures– The manufacturability of the resulting primers (the resulting primers should

not contain long homopolymers)– The nucleotide composition should be between 20%-80% GC

• A biological filtering– SNP filtering: no known SNP (dbSNP 138) is allowed in a primer if its Minor

Allele Frequency (MAF) is greater than 5%. If MAF < 5%, SNPs are allowedanywhere in the primer.

• An off-target analysis to minimize off-target hybridization• An overlap analysis to reduce the number of primers (minimal tiling path),

because a higher overlap implies a higher cost

The tiling algorithm selects a subset (a tiling) of the input amplicons that meets thefollowing criteria:

• Covers as much of each target sequence as does the original input• Has many fewer amplicons than the input set• Maximizes the quality of the amplicons

To do this, the tiling algorithm performs the following steps:

1. Creates an overlap graph of candidate inserts.2. Assigns a cost to each edge.3. Returns the tiles from the least-cost path from source to sink.

The designpipeline

Tiling algorithm

Appendix B Supplemental informationPipeline detailsB


The output from the tiling algorithm is used as input for the pooling algorithm.

Improvements in the tiling algorithm have significantly increased the in silicocoverage of the designs. The users are enabled to choose between in silico and assayperformance.

The pooling algorithm assigns each tile (amplicon) to a pool, subject to requirementsthat allow each pool to be multiplexed.

To assign each tile to a pool, the pooling algorithm performs the following steps:

1. Sorts amplicons by decreasing priority.2. Starts with one available pool.3. Empties all available pools.4. For each sorted amplicon:

a. If there is at least one pool in which the amplicon can be multiplexed, thealgorithm puts the amplicon into the first compatible pool that maximizes thedistance between the amplicon and any other amplicon in the pool.b. If a new pool can be added, the algorithm adds a new available pool andreturns to step 3.c. If a new pool cannot be added, the algorithm puts the amplicon into theoverflow (unpooled) list.

• The tiling algorithm ensures that the PCR pools cover as much of the targets asdo the candidate amplicons supplied to it.

• The pooling algorithm generates a very small number of PCR pools.• The primers in a pool do not interact.• Everything runs quickly and with reasonable memory resulting in faster design

creation.

Hotspots pipeline

Single pool designs represent cost and handling advantages over panels that requiretwo or more pools of primers. Designs targeting small genomic regions such as SNPsand small indels are well suited to fit in a single pool because those regions can becovered by non-overlapping amplicons.

In standard designs the "tiling" stage of the pipeline is when amplicons are selected tocover the target regions. Because the regions are often larger than a single amplicon,several amplicons are required to cover one particular target. This process results in aset of overlapping amplicons that, if put together, are prone to interact with each otherduring the sequencing process. The "pooling" stage is when as many pools as neededare created to avoid these interactions.

The hotspots pipeline includes special algorithms that allow in the pooling stage thecreation of a single pool of primers with maximum coverage for targets as small asone base, and as large as 50 bases.

Pooling algorithm

Advantages ofpooling and tiling

Appendix B Supplemental informationHotspots pipeline B


The idea behind the hotspots designer can be better understood by looking at thefollowing diagram in which the long line represents a genomic region; a, b, and c arethe amplicons available for covering that region. The red portions of the ampliconsrepresent the primers.

cb

a

In a standard (non-hotspots) Ion AmpliSeq™ panel, the targets are long regions(delimited by arrows in the diagram). The algorithm attempts to find a set of primersat minimum cost to cover the target (amplicons a and b). Amplicons a and b overlap,so this would require two pools to cover the region in question. Forcing the panel tobe in one pool would eliminate amplicon a or b resulting in reduced coverage for theone-pool solution. Using amplicons c and b is not an option because they fail to covera portion of the region between the arrows. In contrast, for a hotspots panel, thetargets are small genomic regions (marked with dots over the line representing thegenome), the hotspots pipeline would actually select non-overlapping amplicons cand b to cover the submitted targets. Non-overlapping amplicons can be put togetherin a single pool of primers.

Appendix B Supplemental informationHotspots pipelineB


Ion Chip capacities for Ion AmpliSeq™ DNA libraries sequenced atequal depths

The number of combined libraries that can be accommodated in a single sequencingrun depends on the chip, the balance of barcoded library concentration, and thecoverage required.

For a given chip, as the number of amplicons increases, the number of libraries thatcan be accommodated per sequencing run decreases. This relationship is shown in thefollowing table. The numbers in the following table serve as a guide for approximatecapacities. As the number of libraries per chip increases, it becomes more difficult tobalance the reads between libraries. In addition, libraries from FFPE tissue tend toproduce more variable results. We suggest combining fewer libraries initially anddetermining real limits empirically.

Ion Chip capacities for Ion AmpliSeq™ RNA libraries

We recommend that you plan for an average of 5,000 reads per amplicon for an IonAmpliSeq™ RNA library targeting 1– 200 genes. The actual sequencing depth that isrequired depends on the expression levels of the gene targets in your sample RNA, soscale the sequencing depth to accommodate your sample type and research needs.

For panels containing fusion detection primer pairs, higher library multiplexing ispossible as most targets will not be present, and therefore will not create librarymolecules. For most fusion detection assays, only ~250,000 reads/library are required.

Use the following formula and chip capacity table to provide initial guidance formultiplexing RNA-derived gene expression libraries on Ion sequencing chips.

Number of libraries sequenced per chip = Chip capacity in reads

(Sequencing depth) (Number of primer pairs)

These recommendations serve as suggestions only and the actual capacity tomultiplex libraries is determined by the expression levels of the genes included inyour Ion AmpliSeq™ RNA panel. The expression levels of the individual genes canvary by input RNA type as well. We suggest using the formula for new panels anddetermining actual multiplexing limits empirically.

Frequently asked questions (FAQs)

1. How does the software accommodate intronic regions?When you submit a gene to design, only exons are used as targets. To designacross the whole gene (exons and introns), submit the start and end coordinatesof the gene.

2. When I enter gene symbols, does the design include promoter regions?No. The designer uses exon coordinates as listed by the UCSC Genome Browser.Promoters are not part of the exons and are requested using a BED file describingthe genome coordinates.

3. What is the level of overlap among the primers? Are the overlapping primersin the same tube?Primers in the same tube do not overlap. As our product line evolves in thefuture, a small overlap might be possible.

4. For Ion AmpliSeq™ Designer, are primer sets designed automatically (with acomputer program), without interrogation from a research scientist?The process is an automated pipeline, optimized to provide the maximumcoverage with reliable primer sets.

5. How are the Ion AmpliSeq™ Custom designs verified?Each primer pool goes through a rigorous process to meet strict designspecifications. During the design of our pipeline, we verified a substantialnumber of our custom assays though wet lab testing.

6. Can I use a subset of the Fixed Panels for a custom design?Yes. Clicking the Customize Panel button for the Panel design you are workingwith creates a starting template where you can delete or add genes or regions.

7. For 200-bp designs, should the BED file that is submitted be in a 175−225-bprange?No, you do not have to select the gene coordinates (BED file) to be 175−225 bp.Ion AmpliSeq™ Designer designs the primer pairs, and provides the appropriateBED file and primer sequences to generate amplicons approximately 200-bp inlength.

8. If I submit two continuous regions (175−225-bp range each) combined as oneBED file, is it possible to get the designed primers for the overlapping region?If overlapping regions are submitted to the design pipeline, internally the regionis concatenated and treated as a single region for design, therefore there is nooverlap. The two regions are reported back in the UI as submitted. Although it ispossible that an amplicon is prorated twice, one time in each original region, thisamplicon (and its primers) only occurs one time in the design (see the plate file).

9. The PDF report from my Ion AmpliSeq™ Cancer Panel runs shows that for thealigned sequence section, we have 0.00% coverage of the genome. Is this resultbecause the fraction of the genome that is covered is so low compared to thehg19 reference that we are not showing sufficient decimal places?If a full reference was used, and you have only tens of Mbs, the coverage is solow that we do not track this low of a percentage.

10. What is a superamplicon?A superamplicon is created when two forward PCRs combined to form one largeamplicon. The pooler algorithm in the pipeline separates primers into separatepools to minimize this occurrence.

Designer FAQs

Appendix B Supplemental informationFrequently asked questions (FAQs) B


11. The BED file specifications state that in a BED file the chrStart number is zero-indexed and the chrEnd number is not included in the feature. Are youfollowing this convention for upload and are the numbers shown in thedesigner 1-indexed or 0-indexed?chromStart - The starting position of the feature in the chromosome or scaffold.The first base in a chromosome is numbered 0.chromEnd - The ending positionof the feature in the chromosome or scaffold. The chromEnd base is not includedin the display of the feature. For example, the first 100 bases of a chromosome aredefined as chromStart=0, chromEnd=100, and span the bases numbered 0-99.

12. Can you describe further how the Ultraplex technology works?Development work from over a decade allows us to produce primer designs thatallow simultaneous amplification of many amplicon targets. A unique chemistryhas been developed for Ion AmpliSeq™ libraries that allows removal of anyprimer-dimer that is formed, along with most of the primer itself from theamplified template. This removal makes sequencing efficient by not wastingbases on non-informative primer sequence, and allows for clean sequencingreactions.

13. Do your designs account for the presence of pseudogenes?Yes. The pipeline first attempts to design primers that only match the target, andnot the pseudogene (or duplicate) versions. If the target gene is not covered inthe first rounds of primer selection, then the match parameters are relaxed, forthe sake of coverage, in later rounds, attempting to maintain the uniqueness ofthe inserts.

14. If two amplicons overlap, do the primers produce a large product in additionto two small products?The pooling step in the design is optimized to minimize the interference betweenoverlapping amplicons. Overlapping amplicons are segregated into differentpools.

15. Why is my gene not accepted for design?There are several reasons why your gene is not accepted:

a. A gene must be part of the UCSC Reference Gene dataset.b. A gene must have at least one coding transcript.c. A gene must not map to more than one genomic location (including

pseudoautosomal genes (PAR1,2)).d. A gene must not map to unassembled contigs or alternate assemblies -

examples for human include: chrUn_gl000228, chr4_gl000194_random andchr6_cox_hap2.

16. Which sequence versions does Ion AmpliSeq™ Designer use in itscomputations?DNAHuman Genome* - Feb. 2009 (hg19, GRCh37), Mouse Genome* - Dec. 2011(mm10, GRCm38), Gene targets correspond to RefSeq v63, Hotspots targetscorrespond to dbSNP v138 (for human and mouse) and COSMIC v68 (availableonly for human), RNAHuman RNA Canonical RefSeq Transcripts* - Feb. 2009(hg19, GRCh37), HGNC Database, HUGO Gene Nomenclature Committee(HGNC), EMBL Outstation - Hinxton, European Bioinformatics Institute,Wellcome Trust Genome Campus, Hinxton, and Cambridgeshire, CB10 1SD, UKhttp://www.genenames.org, 11/2012

Appendix B Supplemental informationFrequently asked questions (FAQs)B


General Ion AmpliSeq™ On-Demand Panel design questions

1. Why can I order only 500 genes in an On-Demand panel?For this version of the software, we have set an ordering limit to 500 genes or15,000 amplicons per panel due to manufacturing restrictions. As we continue tomake improvements this limit is likely to increase and larger designs may beordered.

2. Why is there a limit on the number of genes that I can add to my On-Demandpanel?Because the order limit is set at 500 genes per panel, it becomes impractical toallow a large number of genes into the Grid or Table view, which need to bedeselected to make the design orderable. For this reason we have introduced alimit on the number of genes that can be added to an On-Demand panel.

3. Can I edit the content after I have created a design?Yes, an On-Demand design can be edited after it has been created as long as ithas not been ordered, or a Spike-in Panel created. This is different from Made-to-Order designs, which can only be edited in the "Draft" mode, and become lockedafter the job has been submitted and the Results reported.

4. Can I download my list of targets after I have created a design?Yes, select the "Export targets" button to download the list as a CSV file. Thisexports all the targets that are displayed in the user interface (Selected,Deselected, Added).

5. After I've created a design, can I add more content from a Disease ResearchArea (DRA)?Not directly. Currently we do not allow addition of DRA content to an existingdesign, only to new designs. The workaround is to create a new design with thedesired DRA content, and then export the list of targets. You can then upload thislist to the desired existing On-Demand design.

6. What are the genes that are ordered when I click the “Order” button?When you click the "Order" button, only genes that are available as On-Demandgenes, and which you select are ordered. If you create a Spike-in Panel, that panelneeds to be ordered separately by visiting the results page of that panel.

7. Can I edit my design after I have placed an order?No, after you have placed an order, the design cannot be edited because thenecessary files needed for analysis by Torrent Suite™ and Ion Reporter™ Softwareneed to remain in sync with the material you ordered. If you need to edit yourdesign, select the "Clone" option. A new IAD number is then assigned to yourdesign, and you have the option to edit the design content.

8. Can I reorder a design after I’ve placed an initial order?Yes, you can always go back to your ordered design and place a new order.

9. What is the annotation source and version that is used to recognize genesymbols when creating an On-Demand Panel?The source of annotations is refGene, and the version that we are using is versionv74.

10. Are untranslated regions (UTRs) included with an On-Demand gene?No, only the coding DNA sequence (CDS) region of a gene is included as part ofan On-Demand gene design.

11. Are UTR-only genes supported? What about pseudogenes?No, only genes containing CDS regions are supported. At this time, pseudogenesare not supported.

On‑DemandPanels FAQs



12. What is the padding used for On-Demand gene designs?The padding for every On-Demand gene design is 5 bp on the 5’ and 3’ ends.

13. Can I share my design with a collaborator the same way I do with a Made-to-Order design (also known as Custom designs)?We currently do not support an easy share mechanism for sharing the designwith collaborators. However, you can export the list of targets, and share that listwith your collaborator. The design they create will be identical to yours if the listof targets is the same.

14. What is “in silico” coverage?“In silico” coverage is defined by the percentage of bases that are covered by thetiling of amplicons. This number is a computer-based calculation and should notbe confused with experimental coverage, which represents the actualperformance of the panel in the lab.

15. What is "Gene uniformity"?The number of reads spanning is counted for each base across all padded codingexons of a gene. An average value is calculated for all the bases, and thepercentage of bases with read counts above 20% of the average value is definedas "Gene uniformity".

16. Have you checked for all possible gene combinations to test for primer-primerinteractions?No, the number of possible combinations is astronomical and it is not possible totest for all possible combinations in the lab. What the team has done is usecomputer-based searches to reduce as much as possible the occurrence of primer-primer interactions. In addition, the genes have been synthesized in large genebatches, and we have observed less than 1% amplicon drop-out due to suspectedprimer-primer interactions.

Disease Research Areas (DRAs)

1. What are the sources used for creating the associations for the various DiseaseResearch Areas in the tool?The sources include DisGeNET (http://www.disgenet.org), Unified MedicalLanguage System (https://www.nlm.nih.gov/research/umls/) and MedicalSubject Headings (MeSH).

2. What algorithm was used to create such associations?An in-house gene scoring algorithm was used to create these associations. Detailsof the algorithm are proprietary.

3. What does the "Score" mean?The "Score" ranks the relationship between a gene and a disease. It takes intoaccount both the strength and number of gene-disease pairs.

4. Can I preview the content of a DRA before creating a design?No, a preview of the gene content is not available at this time. You need to createthe design to view the gene content.

5. Can I pre-select the gene content of a DRA before creating a design?No, gene content cannot be pre-selected. You can only select full DRA categoriesby clicking the box on the right, and then edit the gene content once the design isin the On-Demand Grid or Table views.

6. What is the number in parentheses next to each DRA?The number in parentheses ( ) denotes number of genes in the group.



http://www.disgenet.org

https://www.nlm.nih.gov/research/umls/

7. The gene count doesn’t seem to add up. Why is that?Gene counts often do not add up as the sum of the subcomponents because oneor more genes can belong to multiple DRAs.

8. My favorite gene is not present in a particular DRA. Why is that?Genes are scored based on their degree of association to a particular DRA by ouralgorithms that have aggregated the data. If your gene is not present, it is likelybecause the observed associations are below our threshold, or outside of thesources we used. Contact our support team ([email protected]) if you are aware of strong evidence demonstratingthat a gene should be included in a specific category.

9. What are "ACMG Recommendations…"?American College of Medical Genetics and Genomics (ACMG)Recommendations for Reporting of Incidental Findings in Clinical Exome andGenome Sequencing.

10. What are "Newborn Screening Conditions" or "Newborn Screening" genes?These are genes associated with conditions listed in the Recommended UniformScreening Panel (RUSP) for newborns.

IGV Viewer

1. What is the "Expected coverage" track in the IGV viewer?The "Expected coverage" track reflects the number of reads that were observedfor each amplicon of each targeted gene during our verification experiments.This track should only be used as general guidance of the likely performanceobserved when running the experiment. Values are likely to be different when anew assay is performed, but the general coverage trend should remain.

2. What are "Missed regions (if any)"?The "Missed regions" are regions where tiling of a high specificity amplicon wasnot possible due to local environment complexity. We have made every effort tominimize the occurrence of these regions in our On-Demand designs.

3. What is the scale on the Y-axis?The Y-axis represents the experimental coverage, which has been normalized to100.

4. Can I use coordinates to navigate the IGV viewer?No, the IGV viewer has been limited to focus on your gene of interest. In the GridView, click a gene and the IGV viewer is updated automatically and centered onthat gene.

5. I’ve noticed that occasionally, the "Expected coverage" track for an amplicondoes not appear to contain information. Why is that?All amplicons in the design contain reads that are visualized in the "Expectedcoverage" track. If reads are not present, they are highlighted in the "Missedregions (if any)" track. It can happen that, if the number of reads covering anamplicon is relatively small in comparison to neighboring amplicons, the"Expected coverage" track appears empty. However, if you change the scale to alower value, you are then able to visualize the lower number of reads.

6. Why do some amplicons have very few reads in the "Expected coverage" track,versus others that have lots of reads?To achieve the most coverage (sensitivity), there is a sacrifice on specificity. So insome instances primers can either bind less tightly, or bind off-target, therebyreducing the number of amplicon reads at the desired region.



Spike-in Panels

1. What are Spike-in Panels?Spike-in Panels are high concentration Made-to-Order Panels that are used toextend the target range to be sequenced to include genes not available as On-Demand genes. Select the "Learn more" link for more information.

2. What is the benefit of a Spike-in Panel?Because the number of genes available as On-Demand genes is limited, a Spike-in Panel enables a user to sequence all the targets initially wanted in a singletarget amplification reaction.

3. What are the limitations of a Spike-in Panel?The limitations of Spike-in Panels involve the number of genes that can beincluded, and possible reduction in current expected coverage performance. Thesize of a compatible Spike-in Panel is limited to 123 amplicons per pool, for atotal of 246 amplicons. Any designs exceeding this limit will not be compatible.

4. How are Spike-in Panels different from Ion AmpliSeq™ On-Demand Panels?Spike-in Panels follow our Made-to-Order process and are synthesized de novofor every order, and the number of reactions is typically large (between 750 to3,000 reactions). On the other hand, On-Demand Panels have been optimized,pre-manufactured, tested and verified, and are available in small reactionnumber batches. On-Demand Panels also contain data that can be visualized inour integrated IGV viewer available in the Grid view.



1. When should I use Ion AmpliSeq™ HD (ASHD) and not "regular" IonAmpliSeq™ (AS)?It depends on the application. If you have an application that requires ultra-highsensitivity, then ASHD is recommended. If you have applications that requirehigh multiplexing, then regular AS is the preferred option.

2. What is the maximum number of amplicons per pool that are supported byASHD?ASHD currently supports up to 500 amplicons per pool with a 2-pool maximumof 1,000 amplicons total. This limit is enforced in AmpliSeq.com.

3. How many reactions worth of material can I expect in my order of an ASHDpanel?The approximate number of reactions worth of material provided for ASHDpanels is 3,000 reactions.

4. Designs are only available for cfDNA (75–100 bp amplicons) and FFPE(125-175 bp amplicons), what about Germline applications (125-275 bp and125-375 bp amplicons)?Germline applications may be considered in the future, depending on therelevance of use of ASHD technology.

5. What are the variant types supported by ASHD?The current supported variant types are, SNVs, small indels, fusions from apredesigned list, and CNV through design best practices available in AmpliSeq.com.

6. What happens if my desired fusion is not available in AmpliSeq.com?In this case, a request to the AmpliSeq Custom Services team should besubmitted. Contact your local sales or support representative to learn more.

7. Does the AmpliSeq Custom Services team support specialty designs forASHD?Yes, the AmpliSeq Custom Services team is supporting specialty designs forASHD. Submission of specialty ASHD designs to the AmpliSeq Custom Servicesteam should follow the same path for AS design requests, which involvescontacting your sales or field support contacts for help.

8. Only gene expression controls are available when creating a fusion design,what about custom designs for gene expression assays, are these supported byASHD?Automated gene expression designs are not currently supported in AmpliSeq.com. However, custom gene expression designs can be created by theAmpliSeq Custom Services team. Contact your local sales or supportrepresentative to learn more.

9. The new Oncomine cf PanCancer panel contains DNA and RNA targets in 1-pool, can you create a similar design with ASHD?Yes, but only through our AmpliSeq Custom Services team. Designs that arecreated in AmpliSeq.com are limited to 1-pool for DNA hotspots, 1-pool forRNA fusions, and 2-pools for DNA gene designs.

10. Why are the FWD and REV primers kept in separate pools?The primers used in ASHD are more complex than for regular AS, so it has beenrecommended to keep them in separate pools for storage and long term stability.FWD and REV primers should only be mixed at the time the libraries are created.See the Ion AmpliSeq™ HD Library Kit User Guide (Pub. No. MAN0017392) formore information.

Advanced features and tools

Ion AmpliSeq™ Designer links the output designed BED file directly to the UCSCGenome Browser automatically configured with the dbSNP and Repeat Maskerannotation tracks. Although this allows you to determine if the regions were filteredbased on either repeat regions or SNPs under the 3' primer, the designer also filters forother reasons. This section of the User Guide offers some suggestions for using otherbioinformatics tools to determine the quality of the design, and for diagnostic andresearch purposes.

One common reason Ion AmpliSeq™ Designer filtered the region would be that it is anon-unique sequence and would hybridize in other areas of the genome and thus bedeleterious to your reaction. BLAST, the Basic Local Alignment Search Tool, findsregions of local similarity between sequences.

1. Using the UCSC Genome Browser, enter the region that has been filtered in theresults of your design.
