MRP2 (ABCC2) Transporter Assay

The MRP2 transporter is an efflux transporter that is encoded by the ABCC2 gene. MRP2 is also known as Multidrug resistance protein. MRP2 is highly expressed in the liver on the apical side of the bile canaliculus in hepatocytes. MRP2 serves to facilitate the biliary excretion of substrates.

BioIVT offers MRP2 substrate and inhibition assays in inverted vesicles. We offer a wide range of studies including single concentration screens up to full kinetic studies to determine the IC50 for MRP2 inhibitors as well as Vmax and Km values for MRP2 substrates.
