H-2DbC Antibody – Mouse

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 beta2-microglobulin. 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. MHC Class I antigens expressed on thymic epithelial cells regulate the positive and negative selection of CD8+ T cells during T cell ontogeny. The monoclonal antibody 28-14-8 binds to the alpha3 domain of H-2Db in the presence or absence of beta2 microglobulin. It cross reacts with the alpha3 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 but it does not block recognition of H-2Ld-positive target cells by Ly-6G2-positive NK cells.

Small volumes of anti-H-2DbC antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
