Anti-TIGIT, Rabbit IgG, kappa Antibody

Recombinant monoclonal antibody manufactured using Recombinant Platform with variable regions from the hybridoma 4D4 to detect TIGIT expression in mouse. 4D4 is an agonistic anti-TIGIT antibody, and addition of anti-CD3/anti-CD28 stimulated T cells to plate bound 4D4 is known to inhibit their proliferation. Further, 4D4 has been used in order to identify genes that are downstream of TIGIT signaling in Tregs, as TIGIT engagement might modulate the Treg phenotype in tumor tissue.

Recombinant monoclonal antibody to TIGIT. T cell immunoreceptor with Ig and ITIM domains (TIGIT), also known as VSTM3, is a type I transmembrane protein, which belongs to the PVR family of immunoglobulin-like domain containing proteins. It is composed of an immunoglobulin variable domain, a transmembrane domain and an immunoreceptor tyrosine-based inhibitory motif (ITIM). TIGIT is expressed on activated T cells, follicular T helper, memory T cells, and regulatory T cells and NK cells. TIGIT binds to CD155 (PVR) with high affinity and it regulates T-cell mediated immunity via the CD226/TIGIT-PVR pathway. TIGIT also serves as a negative regulator of NK and T cell activation.
