Revvity Human Ctla4/Cd86 Biochemical Binding Assay, 500

Revvity CTLA4 (cytotoxic T-lymphocyte-associated protein 4), also known as CD152, is an inhibitor of the immune response expressed by T cells. CTLA4 and CD28 (stimulatory checkpoints) share the same ligands, namely CD80 (B7.1) and CD86 (B7.2), with CTLA4 displaying a greater affinity than CD28 for both, thus creating effective ligand binding competition. Although CTLA4 can be found on all T cells, it is mainly expressed on Treg (regulatory T cells), where it participates in their inhibition of the immune response. - REVPFZ (Additional S&H Or Hazmat Fees May Apply)
