Recombinant Human CD3 Antibody Stimulates IL-2 Secretion in Jurkat Cells

Human CD3 antibody stimulates IL-2 secretion in Jurkat cells (immortalized human T cell line) treated with 5 ng/mL phorbol myristate acetate (PMA). Antibody-mediated stimulation occurred in a dose-dependent manner, as measured using the Quantikine Human IL-2 ELISA kit. The ED50 for this effect is 8-80 ng/mL.

Background: CD3

The Bio-Techne CD3 antibody is derived from the OKT3 clone and binds specifically to the epsilon subunit of the CD3 complex. CD3 (cluster of differentiation 3) is a protein complex and T cell co-receptor that is critical for the activation of T cells. Specifically, the 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 immunoglobulin 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. The CD3 antigen is present on 68-82% of normal peripheral blood lymphocytes, 65-85% of thymocytes and Purkinje cells in the cerebellum.
