Plasma was then screened using the aptamer-based SOMAscan proteomic assay technology, for changes in expression of 1,310 protein analytes.  Results: Detectable values were obtained for all 1,310 proteins included in the SOMAscan assay.  Conclusion: The SOMAscan proteomics platform is a useful screening tool to evaluate changes in biomarker expression.
