产品详情
The WKH203 monoclonal antibody reacts with rat CTLA-4 (cytotoxic T-lymphocyte- antigen 4) (CTLA-4), also known as CD152. CTLA-4 is an inhibitory receptor acting as a key negative regulator of T-cell immune responses. CTLA-4 protein is expressed by activated T cells and by suppressor T regulatory cells. Rat CTLA-4 is a 223 amino acid long single-pass type I membrane protein (encoded by gene Ctla4) and has a predicted molecular weight of 24.9 kDa. CTLA-4 has structural similarities to the T-cell co-stimulatory protein CD28, and both of these molecules bind to the B7 family members B7-1 (CD80) and B7-2 (CD86). CTLA-4’s affinity for its natural B7 family ligands CD80 and CD86 is significantly higher than the affinity of their cognate stimulatory co-receptor CD28. CTLA-4 plays key roles in induction and/or maintenance of immunological tolerance, thymocyte development, and regulation of protective immunity. CTLA-4 is among a group of inhibitory receptors being explored as cancer treatment targets through immune checkpoint blockade. In the last two decades, extensive research on CTLA-4 has led to the clinical approval of therapeutic antibodies for treatment of advanced metastatic melanoma and liver cancer. The binding of the CTLA-4 antibody to the CTLA-4 protein disrupts the key signaling mechanisms linked to the suppression of T cell activity, triggering T cells readily and enhancing the immune system’s capacity to identify and eliminate cancer.参数
