Circulating Biomarker Core

The Circulating Biomarker Core (CBC) provides development and translation of circulating biomarker assays for basic science research, clinical trials and clinical-grade assays. The CBC operates within the UW Carbone Cancer Center and is affiliated with the CLIA/CAP-accredited University of Wisconsin (UW) Cytogenetics facility at the Wisconsin State Lab of Hygiene. The CBC performs a broad range of liquid biopsy assays, including cell free DNA, immune cell studies and multi-plexed analyses of circulating tumor cells. Active collaborations with UW Engineering and private companies have made cutting edge technologies available for users, depending on research interests. One of these technologies (Salus Discovery, LLC) is currently in use for several multi-institutional clinical trials including cooperative group trials.
