mouse monoclonal IgG2a; MAGE-B1 Antibody (B-9) is an IgG2a κ mouse monoclonal MAGE-B1 antibody that detects MAGE-B1 of human origin by WB, IP, IF and ELISA. MAGE-B1 Antibody (B-9) is available as the non-conjugated anti-MAGE-B1 antibody form, as well as multiple conjugated forms of anti-MAGE-B1 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. The melanoma-associated antigen (MAGE) family consists of a number of antigens recognized by cytotoxic T lymphocytes. The MAGE genes were initially isolated from different kinds of tumors and, based on their virtually exclusive tumor-specific expression in adult tissues, they have been used as targets for cancer immunotherapy. MAGE genes encode for tumor-rejection antigens and are expressed in tumors of different histologic types, but not in normal tissues, with the exception of testis and placenta. Although a large number of MAGE genes have now been identified and extensively studied in tumors of various origin, their function in normal cells remains unknown.
