MDR3cyte™ is a patent-pending assay that is the only physiologically relevant assay available to assess test agent inhibition of human multidrug resistance protein 3 (MDR3). MDR3cyte™ is a hepatocyte-based platform that measures test agent inhibition of MDR3, provides cross-species studies, and offers the ability to investigate the effect of in situ drug metabolism on inhibition; the assay is run without radioactive reagents.

MDR3cyte™ employs a 96-well plate format with liquid chromatography-mass spectrometry quantification. The assay is accurate, reproducible, sensitive, and possesses a wide dynamic range. MDR3cyte™ was developed to be cost competitive and high-throughput.

MDR3cyte™ shows excellent correlation with drugs that cause human drug-induced liver injury (DILI) and MDR3 inhibition. MDR3cyte™ is your assay to test MDR3 inhibition and minimize the risk of unexpected DILI.
