Dissecting complex biology requires a proteomic technology that can measure both broadly (thousands of proteins simultaneously) and deeply (across a wide range of concentrations).
Only the SOMAscan assay can do both, thanks to the distinctive properties of the SOMAmer reagents used in the assay. In essence, the SOMAscan assay overcomes a difficult protein measurement challenge by changing it into a straightforward DNA measurement solution.
Researchers can access the SOMAscan assay for their own investigations either as a service from SomaLogic directly, or by having the SOMAscan assay deployed at their own institution.
Figure: Highlights of the SOMAscan assay.
- SOMAmer reagents attached to streptavidin beads bind to proteins in the sample mix
- The proteins that are bound to their specific SOMAmer reagents are then biotinylated
- The SOMAmer-protein complexes are released by photocleaving the linker, and non-specific SOMAmer-protein complexes are separated (center pair)
- Biotinylated proteins are bound to a second streptavidin bead
- Bound SOMAmer reagents are removed from their protein targets
- SOMAmer reagents are collected and denatured
- SOMAmer reagents are measured using standard DNA analysis techniques like microarrays
