Product Details anti-CD3 epsilon Antibody

Target: CD3 epsilon (CD3E)

Reactivity: Mouse

Host: Armenian Hamster

Clonality: Monoclonal

Conjugate: This CD3 epsilon antibody is un-conjugated

Application: Flow Cytometry (FACS), Western Blotting (WB), Immunoprecipitation (IP), Immunohistochemistry (Frozen Sections) (IHC (fro)), Immunohistochemistry (Formalin-fixed Sections) (IHC (f)), Blocking Reagent (BR), Immunohistochemistry (Zinc-fixed Sections) (IHC (zinc))

Brand: BD Pharmingen™

Characteristics: The 145-2C11 antibody reacts with the 25- kDa ε chain of the T-cell receptor-associated CD3 complex, which is expressed on thymocytes, mature T lymphocytes, and NK-T cells. The cytoplasmic domain of CD3e participates in the signal transduction events which activate several cellular biochemical pathways as a result of antigen recognition. Soluble 145-2C11 antibody can activate either unprimed (naive) or primed (memory/preactivated) T cells in vivo or in vitro, in the presence of Fc receptor-bearing accessory cells. In contrast, plate-bound 145-2C11 can activate T cells in the absence of accessory cells. Soluble 145-2C11 antibody has been reported to induce re-directed lysis of Fc receptor-bearing target cells by CTL clones and can also block lysis of specific target cells by antigen-specific CTL's. Under some conditions, T-cell activation by 145-2C11 antibody has been reported to result in apoptotic cell death. The 145-2C11 antibody does not cross-react with rat leukocytes and it has been reported that pre-incubation of thymus cell suspensions at 37 °C for 2-4 hours prior to staining enhances the ability of anti-CD3ε and anti-αβ TCR mAbs to detect the T-cell receptor on immature thymocytes. Immunohistochemical staining of T lymphocytes. The frozen section of normal mouse spleen was reacted with 145-2C11 mAb. The positive staining is represented by the brown labeling of cell-surface membranes of lymphocytes in the periarteriolar sheath.
