IVAL's products and contract services represent three decades of expertise in the application of in vitro experimental systems to evaluate drug absorption, metabolism, transporters, drug-drug interactions and drug toxicity. We focus on hepatocytes as a preferred test system, including co-cultures between hepatocytes and other relevant cell types to suit each investigative purpose. In addition to the broadly available “routine” in vitro ADME studies, we have also developed higher throughput screening assays to aid the selection of best drug candidates for during early phases of drug development. We support a collaborative research environment, and appreciate receiving feedback from you on how to meet your needs, whether it's through contract services, hepatocytes, or training / education.
