Product Summary for Mouse CD3 epsilon Antibody


H-2Kb-specific mouse cytotoxic T-lymphocyte


Detects mouse CD3 epsilon. Binds to lymphocytes from all mouse strains tested and does not react with cells from rats, rabbits, miniature swine, or hamsters.1 Binds to the CD3 epsilon-chain present on T-lymphocyes and thymocytes. Its binding has been characterized with respect to several other monoclonal anti-CD3 antibodies.3,4







Scientific Data Images for Mouse CD3 epsilon Antibody

Mouse CD3e Antibody Stimulates Cell Proliferation antibody in Mouse T Cells.

Mouse CD3 epsilon Antibody Stimulates Cell Proliferation in Mouse T Cells.

Hamster Anti-Mouse CD3e Monoclonal Antibody (Catalog # MAB484) stimulates cell proliferation in mouse T cells in a dose-dependent manner, as measured by Resazurin (Catalog # AR002). The ED50 for this effect is typically 0.1-0.6 µg/mL.

Background: CD3 epsilon

CD3 is composed of five different polypeptides ranging from 16‑28 kDa that are associated with the T cell receptor (TCR) complex and serve as its signal transducing element. The CD3/TCR complex is expressed on T cells and thymocytes. Binding of immobilized anti-CD3 can cause T cell activation that leads to any of several consequences, depending on the conditions. Activation by anti-CD3 in the presence of IL 2 has been reported to induce cell death, apparently via apoptosis.4 The antibody can be used to induce cytolytic activity against non-specific targets and also to block TCR-mediated cytolytic killing.1 145-2C11 has been used in a variety of studies concerned with allograft rejection and graft-vs host reaction in mice.6, 7
