KWS BioTest is now a part of Charles River

In January 2018, Charles River acquired KWS BioTest, a leading contract research organization (CRO) located in Portishead, UK, specializing in in vitro and in vivo discovery testing services for immuno-oncology and inflammatory and infectious diseases. The addition of KWS BioTest’s world-leading immunology expertise makes additional tools available in the increasingly active and promising therapeutic research areas of immunology, oncology, and autoimmune and infectious disease.
