SISCAPA Assay Technologies

SISCAPA Assay Technologies (SAT) specializes in developing, performing, and supporting definitive immunoaffinity-MS assays for protein drugs, targets, and biomarkers. Founded in 2011 by pioneers in the practical application of proteomics for pharmaceutical and diagnostic applications, SISCAPA has since developed hundreds of assays, including mass spectrometry tests. Many of these assays are currently in use in clinical trials, diagnostic tests, and research settings.

In addition to creating custom SISCAPA assays for numerous large and small Pharma and Biotech companies, SISCAPA has also curated a menu of compatible assays for a significant portion of the conventional clinical protein test menu, including mass spectrometry tests. The ultimate goal is to enhance the quality of clinical tests while simultaneously reducing costs.

The team at SISCAPA has spearheaded several notable advances in proteomics, particularly concerning the human plasma proteome.
