Purified (UNLB) Antibody

An epitope in the alpha 3 domain of H-2Db
The "classical" MHC Class I molecules are histocompatibility antigens encoded by the H-2 gene complex and consist of heterodimers of highly polymorphic alpha chains noncovalently associated with the invariant beta 2-microglobulin.3, 4 These antigens are expressed on most nucleated cells but expression varies on different cell types. MHC Class I molecules present endogenously synthesized peptides to CD8+ T lymphocytes, which are usually cytotoxic T cells.5 MHC Class I antigens expressed on thymic epithelial cells regulate the positive and negative selection of CD8+ T cells during T cell ontogeny.3, 6 The monoclonal antibody 28-14-8 binds to the alpha 3 domain of H-2Db in the presence or absence of beta 2 microglobulin.7,8 It cross reacts with the alpha 3 domain of H-2Ld, but not Kd or Dd, and with H-2Dq and/or Lq. The antibody has been shown to block H-2Ld-specific and H-2Ld-restricted antigen-specific lysis of target cells by cytotoxic T lymphocytes,9-11 but it does not block recognition of H-2Ld-positive target cells by Ly- 6G2-positive NK cells.12
