Clone 145-2C11
Isotype Hamster (Armenian) IgG1
Isotype Control Hamster IgG-FITC
Immunogen H-2Kb-specific murine cytotoxic T-lymphocyte (CTL) clone BM10-37
Specificity Mouse CD3ε
Alternalte Name(s) CD3 epsilon
Description CD3ε, a member of the immunoglobulin superfamily of cell surface receptors, is comprised of five invariable chains ranging in size from 16-28 kDa and is closely associated with the T cell antigen receptor (TCR). It is expressed on all T cells of all mouse strains. CD3 plays a major role in signaling during antigen recognition, leading to T-cell activation. The 145-2C11 monoclonal antibody recognizes an epitope on the 25 kDa ε chain of the CD3/TCR complex. In the presence of Fc receptor-bearing accessory cells, soluble 145-2C11 can activate primed and naïve T cell in vitro. 145-2C11 can also induce redirected lysis of specific target cells by CTL clones and it can block lysis of specific target cells by antigen-specific CTL’s. Immobilized 145-2C11 can activate both normal T lymphocytes and cloned T cell lines. Under certain conditions, T cell activation by 145-2C11 may result in apoptotic cell death.
