CD3 epsilon antibody (Biotin)

Catalog No. ABIN2689216

Product Details anti-CD3 epsilon Antibody (Biotin)

Target: CD3 epsilon (CD3E)

Reactivity: Mouse

Host: Armenian Hamster

Clonality: Monoclonal

Conjugate: This CD3 epsilon antibody is conjugated to Biotin

Application: Flow Cytometry (FACS), Immunohistochemistry (Frozen Sections) (IHC (fro))

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. This antibody is routinely tested by flow cytometric analysis. Other applications were tested during antibody development only or reported in the literature. CD3e expression in spleen and thymus. BALB/c splenocytes were simultaneously stained with PE-conjugated anti-mouse CD4 mAb RM4-5 (Cat. No. 553048), PE-conjugated anti-mouse CD8a mAb 53-6.7 (Cat. No. 553032) and biotin-conjugated mAb 145-2C11 (bottom left panel), followed by Avidin-FITC (cat. No. 554057). BALB/c thymocytes were also stained with biotin-conjugated mAb 145-2C11 followed by Avidin-FITC (bottom right panel). Flow cytometry was performed in a BD FACScan™ flow cytometry system.
