SMVT (SLC5A6) Transporter Assay

SMVT is the sodium dependent multivitamin transporter. It is widely expressed in many tissues including the intestines, kidney, heart, lung and the blood-brain barrier.

Creating biotinylated conjugates has been used as a strategy for drugs such as HIV protease inhibitors to exploit SMVT to achieve higher permeability into select organs and penetration across the blood-brain barrier (BBB). SMVT over expressions has been shown in some tumor cells, providing a possible route for increased uptake and targeted distribution of oncology drugs.

BioIVT offers SMVT 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 SMVT inhibitors as well as Vmax and Km values for SMVT substrates.
