Anti-Human TIGIT PerCP-eFluor® 710

Description: The MBSA43 monoclonal antibody reacts to human T cell immunoreceptor with Ig and ITIM domains (TIGIT), which is also known as VSTM3 or WUCAM. This 26 kDa protein is a member of the poliovirus receptor (PVR) family. The expression of TIGIT has been reported on NK cells, regulatory T cells, follicular T helper cells, memory CD4+ T cells, and CD8+ T cells, but it is not expressed on B cells or naïve CD4+ T cells. TIGIT may be upregulated on naïve CD4+ T cells upon activation. TIGIT can interact with certain members of the PVR and PVR-like families, including CD155, and also mediates the interaction of NK and T cells with antigen presenting cells, fibroblasts and endothelial cells that express PVR and PVR-like proteins.
