This antibody reacts with the intracytoplasmic portion of CD3 and stains human T cells in both the cortex and medula of the thymus and in peripheral lymphoid tissues. This antibody is suitable for staining normal and neoplastic T cells in formalin-fixed, paraffin embedded tissues. For tissue staining, antigen retrieval is suggested by boiling tissue sections in 10mM citrate buffer, pH 6.0 for 10 minutes followed by cooling at room temperature for 20 minutes.
This antibody is predicted to react with Sheep, Rabbit, Horse, Chicken, Cow, Cat, Dog, Baboon, and Woodchuck.
Recommended positive controls:
WB - Recombinant human CD3e protein, Jurkat whole cell lysate, Human, mouse and rat thymus tissue lysate|
IHC (P) - Pig and rat spleen tissue, human tonsil tissue, mouse epidydimal fat pad and lymph node tissues, rat infarcted heart and spleen tissues
Flow Cytometry - Human peripheral blood lymphocytes, Jurkat cells
IHC (F) - Mouse brain tissue
The CD3 subunit complex which 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 and 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. The genes encoding the CD3 epsilon, gamma and delta polypeptides are located on chromosome 11. Defects in the CD3 gene are associated with CD3 immunodeficiency.
