Technical Data
MHC Class 1, H2, Db, alpha3 (Biotin)
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 (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). This antibody binds to the alpha3 domain of H-2Db in the presence or absence of beta2 microglobulin (7,8).

Suitable for use in Flow Cytometry, Immunoprecipitation and Complement-mediated cytotoxicity studies. Other applications not tested.

Recommended Dilutions:
Flow Cytometry: 1ug/10e6 cells
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Supplied as a liquid in PBS, 0.09% sodium azide. Labeled with Biotin.
Recognizes an epitope in the alpha3 domain of mouse H-2Db. Crossreacts with the alpha3 domain of H-2Ld, but not Kd or Dd, and with H-2Dq and/or Lq. 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.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
