TIGIT Mouse anti-Mouse, PE, Clone: 1G9, BD, Mouse Monoclonal Antibody, Each

Details

The 1G9 monoclonal antibody specifically binds to T cell immunoreceptor with Ig and ITIM domains (TIGIT) which is also known as, V-set and transmembrane domain-containing protein 3 (Vstm3). TIGIT is a 26 kDa, type I transmembrane glycoprotein that belongs to the poliovirus receptor (PVR) family. TIGIT is expressed on activated and memory CD4 T cells and CD8 T cells, follicular T helper cells, regulatory T cells, and NK cells. Its ligands include the poliovirus receptor (PVR, aka, CD155), poliovirus receptor-related protein 2 (PVRL2, aka, CD112), and poliovirus receptor-related protein 3 (PVRL3, CD113). TIGIT functions as a negative regulator of T cell and NK cell responses including proliferation, cytotoxicity, and the production of proinflammatory cytokines. TIGIT-deficient mice are reportedly more susceptible to developing autoimmune diseases in certain model systems.
