Antigen Specificity: The UCHT1 monoclonal antibody reacts with human CD3e, a 20 kDa subunit of the TCR/CD3 complex. Along with the other CD3 subunits gamma and delta, the epsilon chain is required for proper assembly, trafficking and surface expression of the TCR complex. CD3 is expressed by developing thymocytes and by all mature T cells. Crosslinking of TCR via immobilized UCHT1 results in T cell proliferation.

Our Pacific Orange™ dye is optimally excited by the violet laser, and it is recommended that a 575, 585 or 600 nm band pass filter be used for optimal detection. Pacific Blue™ and Pacific Orange™ dye conjugates can be simultaneously excited at 405 nm and emit at 455 nm and 551 nm, respectively, facilitating two-color analysis.
CD3 complex is crucial in transducing antigen-recognition signals into the cytoplasm of T cells and in regulating the cell surface expression of the TCR complex. T cell activation through the antigen receptor (TCR) involves the cytoplasmic tails of the CD3 subunits CD3 gamma, CD3 delta, CD3 epsilon and CD3 zeta. These CD3 subunits are structurally related members of the immunoglobulins super family encoded by closely linked genes on human chromosome 11. The CD3 components have long cytoplasmic tails that associate with cytoplasmic signal transduction molecules. This association is mediated at least in part by a double tyrosine-based motif present in a single copy in the CD3 subunits. CD3 may play a role in TCR-induced growth arrest, cell survival and proliferation. The CD3 antigen is present on 68-82% of normal peripheral blood lymphocytes, 65-85% of thymocytes 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.
