NTCP (SLC10A1) Transporter Assay

The NTCP transporter is encoded by the SLC10A1 gene. It is also known as the sodium (Na+) taurocholate co-transporting polypeptide. NTCP is expressed in liver hepatocytes on the basaolateral side of the sinusoidal membrane. It serves to bring bile salts and other substrates from the blood stream into the liver.

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