CTLA4 (CD152), Fc fusion, Biotin-labeled

Human secreted CTLA4, Fc fusion protein, also known as Cytotoxic T-lymphocyte-associated protein 4 and CD152. GenBank Accession No. NM_005214, a.a. 36- 162, fused at the C-terminus to the Fc portion of human IgG1 and with a C-terminal Avi-tag, expressed in a HEK293 cell expression system. This protein was biotinylated using AviTag(TM) technology. MW = 42 kDa (monomer). Note: This protein runs at a higher MW by SDS-PAGE due to glycosylation.
