CTLA4 Human, IgG-His, Active

Source: Sf9, Baculovirus cells.Sterile Filtered colorless solution.Cytotoxic T-lymphocyte-associated protein 4 or CTLA4 or CD152 is a receptor that takes part in the immune checkpoint and inhibits immune response. This protein is fundamentally found in regulatory T cells; however, it acts as an enhancer in regular T cells following its activation, this is eminent in cancers. CTLA4 bounds to CD80 or CD86 on the membrane of antigen presenting cells and downregulates transductions. CTLA4 Human produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 368 amino acids (36-161aa) and having a molecular mass of 40.8kDa.CTLA4 is fused to a 242 amino acid hIgG-His-Tag at C-terminus and purified by proprietary chromatographic techniques.
