Snapshot Proteomics™ uses microarrays that contain approximately 20,000 individual human proteins.

Treating the array with a biological sample leads to changes at relevant protein targets.   Because the arrays and test samples are maintained in a near native state, enzymes and proteins maintain their activity allowing for signal amplification and greater sensitivity.  Similar to but distinct from a western blot, specific proteins are spatially separated into unique locations and the individual protein changes can be reported.
