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.

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.
