Monoclonal Anti-B2M Antibody, Mouse IgG2b (BBM.1)

Beta-2-microglobulin (B2M) is a component of the class I major histocompatibility complex (MHC) and involved in the presentation of peptide antigens to the immune system. B2M consists of two β sheets joined by a disulfide bond, which could form amyloid fibrils in some pathological conditions. Increasing evidence has indicated that B2M gene alterations in tumor cells may lower the efficacy of T-cell based immunotherapies by hampering MHC class I-mediated tumor antigen presentation and avoiding T cell recognition.
