BSEPcyte™ is a patented assay (United States patent number 9,772,325) that offers significant advantages over bile salt export pump (BSEP) assays that use membrane vesicle preparations. BSEPcyte™ is a physiologically relevant hepatocyte-based platform that measures test agent inhibition of BSEP or Bsep, provides cross-species comparisons, and offers the ability to investigate the effect of in situ drug metabolism on inhibition; the assay is run without radioactive reagents.

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

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