Human CD152/CTLA4 (GIGA-564) Antibody is a research-grade biosimilar monoclonal antibody. It is a human IgG antibody. Reactivity: Human. Supplied as a liquid in 0.01M PBS pH 7.4. Applications: ELISA, flow cytometry, functional assays and in vivo research. Endotoxin: < 10 EU/mg. Purity: >95% purity as determined by SDS-PAGE. For research use only.
Cytotoxic T-lymphocyte protein 4 (CD152/CTLA4) is a ~24 kDa protein. Inhibitory receptor acting as a major negative regulator of T-cell responses. Acts as a decoy receptor: the affinity of CTLA4 for its natural B7 family ligands, CD80 and CD86, is considerably stronger than the affinity of their cognate stimulatory coreceptor CD28. CD152 is the therapeutic target of ipilimumab (Yervoy).

Biological Activity:
GIGA-564 (0.001-100 ug/mL) exhibits extremely low activity in blocking the binding of CTLA-4 to CD80 and CD86 in ELISA assays [1]. GIGA-564 (5 mg/kg; i.p.; once every 3 days; 3 doses) induces a lower level of peripheral Treg proliferation than Ipilimumab () in hCTLA-4 KI mice bearing MC38 tumors [1]. GIGA-564 (0.3 mg/kg; i.p.; once every 3 days; 3 doses) exhibits excellent anti-tumor activity in hCTLA-4 KI mice bearing MC38 tumors [1]. GIGA-564 (30 mg/kg; i.p.; once every 3 days; 9 doses) induces less toxicity than Ipilimumab () in hCTLA-4 knock-in (KI) and hCTLA-4/hPD-1 double knock-in (KI) mice, as evidenced by lower liver enzyme levels, reduced colitis, and the absence of skin lesions at the tested dose [1].
