SERT (SLC6A4) Transporter Assay

The SERT Transporter Assay is a monoamine transporter protein. SERT is found in brain and many peripheral tissues and is responsible for the active transport of serotonin (5-HT) into neurons, enterochromaffin cells, platelets, and other cells. In brain, SERT is situated both in presynaptic membranes of nerve terminals and in dendritic arbors in close proximity to serotonin-containing cell bodies in the midbrain and brain stem raphe nuclei. SERT mediates rapid removal and recycling of released serotonin following neuronal stimulation.

BioIVT offers SERT 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 determinations for SERT inhibitors, as well as Vmax and Km studies for SERT substrates.
