1x10^6 human PBMCs were surface stained with 0.2 µg Anti-Human CD3 Rabbit Recombinant Antibody (65504-1-RR, Clone: OKT3) (left) and CoraLite®647-Conjugated Goat Anti-Rabbit IgG (H+L) at dilution 1:1,000 or 0.2 µg Anti-Human CD3 Mouse Monoclonal Antibody (Clone: OKT3) (center and right) and CoraLite®647-Conjugated Donkey Anti-Mouse IgG (H+L) at dilution 1:1,000. Cells were then stained with CL488 Anti-Human CD45. Cells were not fixed. Lymphocytes were gated.

Target Information
The CD3 complex, composed of gamma, delta, epsilon, and zeta subunits, is essential for the assembly, trafficking, and surface expression of the T cell receptor (TCR) complex. These subunits are structurally related members of the immunoglobulin superfamily and are encoded by closely linked genes on human chromosome 11. CD3 is expressed by thymocytes in a developmentally regulated manner and by all mature T cells, but not on B or NK cells. The CD3 subunits play a crucial role in transducing antigen-recognition signals into the cytoplasm of T cells. The cytoplasmic tails of CD3 subunits contain a double tyrosine-based motif that associates with cytoplasmic signal transduction molecules, mediating T cell activation through the TCR. Crosslinking of the TCR initiates intracellular biochemical pathways that result in cellular activation, proliferation, and potentially growth arrest and cell survival. CD3 is present on 68-82% of normal peripheral blood lymphocytes, 65-85% of thymocytes, and Purkinje cells in the cerebellum. Decreased percentages of T lymphocytes may be observed in some autoimmune diseases. Defects in the CD3 gene are associated with CD3 immunodeficiency, highlighting its importance in immune function and regulation.
