CD274 [B7-H1/PD-L1] (human)-muIg Fusion Protein

Product description: Protein. Liquid. 50 mM Sodium Phosphate pH 7.5, 100 mM Potassium Chloride, 150mM NaCl, 0.5% Gentamicin sulfate CD274 (B7-H1; PD-L1; Programmed Death Ligand) is a member of the B7 family and is expressed on a variety of tissues including lymphoid cells. It plays an important role in regulation of T cell activation and is involved in progression of cancer, arthritis and HIV infection. CD274 binding to its receptor CD279 (PD-1) on activated T cells can decrease proliferation. Conversely, ligation of CD279 on primed T cells can stimulate IL-10 production. High levels of CD274 present in renal cell carcinoma is associated with poor prognosis. Tumor expressed CD274 can increase apoptosis of tumor specific T cells resulting in better tumor cell survival.
