HIR Priority Areas
1. Genomics
2. Proteomics
3. Analytical chemistry
4. Metabolomics
5. Bioinformatics
Genomics • HiSeq2500, G floor
• Whole-Genome Sequencing: sequence
a whole human genome in a day (2x100bp
reads). Or, in high output mode &
sequence multiple genomes in a single run (2x150bp reads) 176 Gb in ~40h including on board cluster generation and sequencing, with 90.2% of bases at or above Q30, high quality alignment and variant calling.
• Targeted Resequencing: individual custom panels to whole exomes
• Whole-Transcriptome Sequencing: gene expression profiling to deep transcriptional analysis, HiSeq offers unprecedented RNA analysis solutions. Measure abundance of individual transcripts and isoforms, discover new genes, and identify regulatory non-coding RNAs.
• De Novo Sequencing: de novo sequencing of any size genome; NGS of metagenomic analyses
• Epigenetic Regulation: Study DNA-protein interactions and gene regulation using ChIP-Seq, and quantify DNA methylation with single base resolution.
• PacBio SMRT, G floor The PacBio RS II sequencing technology resolves single molecules in real time, allowing observation of structural and cell type variation not accessible with other technologies. De Novo assembly: extra-long read lengths that simplify and improve genome assembly. • Highest N50 • Fewest contigs • Detect structural variation • 99.999% accuracy • Genome finishing at 1/10th the cost Targeted sequencing: common use of targeted sequencing is single nucleotide polymorphism (SNP) detection and validation.
SMRT directly measures individual molecules, using long reads to fully characterize genetic complexity, including rare SNPs, indels, structural variants, haplotypes and phasing. Single molecule resolution allows comprehensive characterization of heterogeneous samples and identification of variation invisible to multi-molecule sequencing technologies. • Benefits: • Compound Mutations and Haplotype Phasing - Multi-kilobase reads facilitate the study of linked mutations
hundreds, even thousands, of bases apart. • Repeat Expansions - Long reads and low bias allow accurate sequencing across repeat expansions, even in low
complexity regions. • Full-Length Transcripts and Splice Variants - Single-molecule resolution and long reads span entire cDNAs, allowing
full characterization of splicing in the transcriptome. • Minor Variants and Quasispecies - Single molecule sequencing simplifies the analysis of mixed populations of
sequences. Exquisitely sensitive and specific. • SNP Detection and Validation - Single molecule sequencing detects and validates SNPs with high accuracy by
avoiding mapping errors and systematic errors.
Base Modification Detection: DNA base modifications are important to the understanding of biological processes such as gene expression, host-pathogen interactions, DNA damage, and DNA repair. (SMRT) Analysis software works by measuring the rate of DNA base incorporation during sequencing. This information, automatically gathered during the sequencing process, is a unique feature of our SMRT technology. Resolve strand-specific modifications - unamplified double-stranded input DNA enables detection of strand-specific modifications such as hemimethylation Single-base resolution - visualize a wide variety of base modifications in high-resolution Integrated sequence and chemical modification detection - epigenetic and other base modification data are gathered in the sequencing process, as an integral part of the sequencing workflow Hypothesis-free detection - no prior knowledge of the modification is needed, allowing discovery of unknown or unexpected modification

Single cell analysis and NGS
• Microfludic single cell analysis enabling profile of multiple single cells for the expression of hundreds of genes in just a few hours, using standard reagents and easy-to-use analysis tools enable hundreds of individual cells to be tested for the expression of hundreds of genes in a few hours. Advantages: • High Sample Throughput—Screen up to 96 single cells across 96
assays in one array. • Produce More Results Faster—Produce 9,216 data points in just
four hours with one array. • Assay Flexibility—Practice tried-and-true techniques such as
TaqMan assays or other common assays.
Microfludic single cell analysis
• Enabling: Measure expression levels of genes, alleles and spliced variants
• Compare tissue or cell type expression levels
• Map transcription initiation sites
• Characterize alternate splicing patterns
• Evaluate post-transcriptional activity
• Discover new transcripts and gene fusions
Proteomics
• 1D & 2D gel, Western blot, ELIZA • FPLC • Typhoon system • Isothermal Titration Calorimeter (ITC): GE Healthcare’s MicroCal (ITC) allows characterization of biomolecular interactions by
providing direct, label-free measurements of binding affinity and thermodynamics. In a single ITC experiment, you can determine binding affinity (KD), stoichiometry or
number of binding sites, enthalpy (ΔH), and entropy (ΔS). Thermodynamic data, specifically ΔH and ΔS, reveal the forces that drive complex formation and mechanism of action. Thermodynamic measurements provide information on conformational changes, hydrogen bonding, hydrophobic interactions, and charge-charge interactions.
provide valuable information about binding interactions, molecular stability, protein folding, and enzyme kinetics.
