Rules-Based Medicine has launched its OncologyMAP product for the quantitative measurement of 101 cancer-related proteins in serum.

RBM released the platform to a limited number of customers last October and is now making it available worldwide. The test is validated to clinical laboratory standards, which allows protein biomarker discovery research to be more easily translated to clinical trials, the company said.
