ProteOn XPR36 Protein Interaction Array System

Instrument


www.bio-rad.com

The ProteOn XPR36 protein interaction array system is an SPR optical biosensor that provides real-time data on the affinity, specificity, and interaction kinetics of protein interactions. Using proprietary XPR technology, a unique approach to multiplexing, this system generates a 6 x 6 interaction array for the simultaneous analysis of up to six ligands with up to six analytes. The ProteOn XPR36 system increases the throughput, flexibility, and versatility of experiment design, enabling the completion of more experiments in less time:

Analyze up to 36 different protein interactions in a single run, on a single chip

Perform a complete kinetic analysis in a single run

Measure a variety of experimental conditions simultaneously in parallel

Screen multiple panels of analytes

The ProteOn XPR36 system includes all of the components required for interaction analysis: instrumentation, software, sensor chips, buffer and reagent kits, and protocol

development kits. User-friendly ProteOn Manager software uses a flexible, guided approach to coordinate instrument control, experiment setup, and data analysis.

Flexible Sample ConfigurationThe autosampler accommodates the ProteOn sample rack and ProteOn microplates. The sample rack holds 72 ProteOn sample vials with pierceable caps. The microplate layout accommodates two 96-well ProteOn standard microplates or ProteOn deep-well microplates. The illuminated autosampler platform is also temperature controlled.

Instrument Status LEDsA series of LEDs indicate instrument communication with ProteOn Manager software, temperature of the autosampler and sensor chip chambers, experiment status, and autosampler status.

Bar Code RecognitionBar codes provide automatic recognition of sensor chip type, expiration date, and lot number. Bar codes also provide a usage record and direct linkage between the chip identification and its associated protocol and experiment.

For more information, request bulletins 5390 and 5413.

Advanced Optics and Interspot Referencing The ProteOn XPR36 protein interaction array system uses imaging technology to detect the SPR response for each spot on a sensor chip. The ProteOn XPR36 system measures a total of 78 spots: 36 spots represent the interaction data from the 6 x 6 array, and 42 interspot references can be used for reference subtraction.

Innovative Fluidics and Parallel ProcessingThe 6 x 6 interaction array and microfluidics system provide efficient parallel processing of multiple samples. Two sets of six 0.5 ml syringe pumps (sample syringes and buffer syringes) operate in unison for parallel aspiration and injection of six samples or reagents.

The buffer compartment holds two 2 L bottles for running buffer, and valve control between the two buffer bottles is hardware and software controlled. An in-line degasser removes bubbles from the buffer as it moves through the fluidics system.
