nRichDx: Revolution System

nRichDx has launched its high-yield sample prep Revolution System. The Irvine, California firm designed the in vitro diagnostic system to increase liquid biopsy-based test sensitivity by delivering more target input for molecular assays. Researchers can currently use the platform to extract cell-free DNA from plasma and urine, followed by eventual applications for circulating tumor cells, exosomes, and total cell-free nucleic acid in the development pipeline.
