Immunogen Human peripheral blood lymphocytes.
Clone MEM-92
Isotype IgM
Specificity The antibody MEM-92 reacts with epsilon chain of human CD3 complex, a part of a biggermultisubunit complex of the T cell receptor (CD3/TCR) expressed on peripheral blood Tlymphocytes and mature thymocytes.HLDA IV., WS Code T 97
Purification Purified from hybridoma culture supernatant by protein-A affinity chromatography.
Purity > 95% (by SDS-PAGE)
Alternative Name CD3E
Background CD3 complex is crucial in transducing antigen-recognition signals into the cytopasm of Tcells and in regulating the cell surface expression of the TCR complex. T-cell activationthrough the antigen receptor (TCR) involves the cytoplasmic tails of the CD3 subunits CD3gamma, CD3 delta, CD3 epsilon and CD3 zeta. These CD3 subunits are structurally relatedmembers of the immunoglobulins super family encoded by closely linked genes on humanchromosome 11. The CD3 components have long cytoplasmic tails that associate withcytoplasmic signal transduction molecules. This association is mediated at least in part by adouble tyrosine-based motif present in a single copy in the CD3 subunits. CD3 may play arole in TCR-induced growth arrest, cell survival and proliferation.The CD3 antigen is present on 68-82% of normal peripheral blood lymphocytes, 65-85% ofthymocytes and Purkinje cells in the cerebellum. It is never expressed on B or NK cells.Decreased percentages of T lymphocytes may be observed in some autoimmune diseases.
Research Area Immunology, Adaptive Immunity, Hematopoietic Progenitors, Hematopoietic Stem Cells, CD Antigens, Surface Receptors of Immune Cells
Application Notes Functional Application: The antibody MEM-92 in solution induces early responses of T cell activation (tyrosinephosphorylation, calcium elevation, Erk activation and expression of activation antigens), butit is unable to induce T cell proliferation.
