These cell surface proteins are responsible for the regulation of antigen-specific immunity in humans. HLA genes are highly polymorphic, allowing them to fine-tune the adaptive immune response. HLAs corresponding to MHC class I (HLA-A, B, and C) present small peptide antigens from inside the cell, approximately 8 to 10 amino acids in length, to CD8 T lymphocytes in order to activate a cytotoxic T cell response. HLAs corresponding to MHC class II (HLA-DP, DM, DO, DQ, and DR) present antigens from outside of the cell, approximately 15 to 24 residues in length, to CD4 T helper cells, which in turn secrete cytokines and stimulate B cells to produce antibodies to that specific antigen. HLAs corresponding to MHC class III encode components of the complement system (1,2). The L243 antibody reacts with a member of the human MHC Class II antigens, HLA-DR. The HLA-DR antigen is expressed on B lymphocytes, activated T lymphocytes, activated NK cells, monocytes, macrophages, other antigen presenting cells and progenitor cells (3).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nDRA; histocompatibility antigen HLA-DR alpha; HLA class II histocompatibility antigen, DR alpha chain; HLA-DRA; HLA-DRA1; major histocompatibility complex, class II, DR alpha; MHC cell surface glycoprotein; MHC class II antigen DRA; MLRW\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nSource\/Isotype: Mouse IgG2a kappa","brand":"CST","offers":[{"title":"Default Title","offer_id":46800558555305,"sku":"92482S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-92482s","provider":"Iright","version":"1.0","type":"link"}
