Monoclonal antibody directed against HLA-A2 histocompatibility antigen, used to aid investigation into foreign antigen presentation and HLA mRNA production. Background and Research Application Human Leukocyte Antigens (HLA) are highly polymorphic proteins that are involved in the presentation of antigens to the T-cell receptor. There are two classes of HLA antigens, class I (HLA-A, HLA-B and HLA-C) and class II (HLA-D). The polymorphic HLA-A, -B, -C glycoproteins have a molecular weight of 43,000 daltons and are expressed on the surfaces of nearly all somatic cells, except red blood cells. This antibody can be used for HLA typing. Anti-HLA-A2 BB7.2 antibody recognizes human leukocyte antigen (HLA) A2 which is a subset of MHC-class I molecules encoded by the A.02 allele. It recognises an epitope at the C-terminus of alpha-2 helix and a turn on one of the underlying beta strands. Anti-HLA-A2 BB7.2 binds to an epitope at the C-terminus of the alpha-2 helix within the human HLA-A2 histocompatibility antigen. This antibody has exhibited blocking activity. Anti-HLA monoclonal antibodies can help identify in vitro translation production from HLA region mRNA, alongside isolating specific mRNA via precipitation or binding of polysomes. Anti-HLA-A2 can aid study within the immune response, including the presentation of foreign antigens to the immune system. |

| Notes |
Production Details Purified using multi-step affinity chromatography with protein A. Storage Conditions Store at -20 degrees frozen. Avoid repeated freeze/thaw cycles. Points of Interest Anti-HLA-A2 was reported to have recognised HLA-A28. This antibody tested positive for complement dependant cytotoxicity and protein A binding. BB7.2 fixes complement and is cytotoxic for peripheral blood leukocytes and lymphoid cell lines. Chawla et al., 2016 - BB7.2 blocked the HLAA2/T cell receptor interactions and specifically killied target cells by E75-CTL. Concentration 1mg/ml as standard |
