Description

Rabbit Monoclonal Antibody

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 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.
