Isotyp: IgG2a

Klon: 28-14-8

Beschreibung: An epitope in the 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 chains noncovalently associated with the invariant 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 3 domain of H-2Db in the presence or absence of 2 microglobulin.7,8 It cross reacts with the 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.

Anwendungen

Applikationshinweise: Working Dilutions: Flow Cytometry: Purified (1 ug/10^6 cells), Fluorescein (1 ug/10^6 cells), Biotin (1 ug/10^6 cells), R-phycoerythrin (0.5 ug/10^6 cells). Since applications vary, you should determine the optimum working dilution of the product that is appropriate for your specific need.

The R-phycoerythrin (R-PE) conjugate is supplied as 0.1 mg in 1.0 mL of PBS/NaN3 and a stabilizing agent. Store at 2-8C. Do not freeze! The low endotoxin, azide-free (LE/AF) antibody is supplied as 0.5 mg purified immunoglobulin in 1.0 mL of PBS. Aliquot and store at or below -20C. Protect conjugated forms from light. Aliquot and freeze the low endotoxin, azide-free product at -20C immediately upon receipt. Each reagent is stable for the period shown on the bottle label if stored as directed. WARNING Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
