useful for detection of normal peripheral blood T cells, some neoplastic T cells in human.

Anti CD3 Monoclonal Antibody (Clone No. NU-T3)


The CD3-T cell receptor (TCR) complex plays a central role in the recognition of the antigens and subsequent signal transduction and activation of immunocompetent T lymphocytes. There are two types of TCR differentiated by their heterodimers, namely TCRαβ and TCRγδ. The CD3 antigen is comprised of multiple subunits (CD3γ, CD3δ, CD3ε, and CD3ζ). The variable immunoglobulin domains of TCRαβ (TCRγδ) bind to the ligand, whereas the cytoplasmic tails of the CD3 subunits interact with cytosolic-signalling proteins. This antibody is specific to human T cell associated-antigen and will be useful for detection of normal peripheral blood T cells, some neoplastic T cells in human.
