The In Vitro Services group at Charles River provides information to complement the metabolic, toxicokinetic, and bioanalytical investigations undertaken in pharmaceutical product development. Our in vitro experts provide qualitative and quantitative data to address a variety of regulatory questions. In vitro studies can be conducted with both radiolabelled and non-radiolabelled test articles as required.
