NEW YORK (GenomeWeb News) – On-Q-ity today announced it has raised $5 million in financing and it has appointed Michael Stocum as the company's president and CEO.

The microfluidic chip, called the On-Q-ity Circulating Cancer Capture and Characterization Chip, or C5, uses both antibody affinity and size to filter CTCs from normal blood. In a study comparing C5 and a chip using antibody affinity alone, On-Q-ity's dual capture chip "greatly improved" capture rate over the comparator.

In an interview with GenomeWeb Daily News, On-Q-ity CEO Mara Aspinall touted the advantages of the firm's platform and discussed its potential to monitor patients in clinical trials at a level not currently possible.

LabCorp will market the platform to biopharma researchers conducting clinical studies of oncology drugs.
