SOMAscan Assay Support

SomaLogic’s SOMAscan assay uniquely detects and measures greater than 1,300 analytes across a wide dynamic range in small volumes of multiple biological sample types. Our approach enables scientists to find the critical biomarkers that reflect the “real-time” biology of the disease or condition being studied

The SOMAscan assay has been tested thoroughly, and has been applied to over 70,000 samples across more than 40 diseases and conditions to date (an annotated list of publications can be found here).
