CD3 Biotin

CD3ε is a 20kD peptide chain, which together with CD3λ, CD3δ, and CD3ζ, and a T cell receptor (α/β or γ/) form the CD3/T-cell receptor complex. It is a specific marker for T lymphocytes, NK T cells, and some thymocytes. Crosslinking of TCR initiates an intracellular signaling cascade resulting in cellular activation and proliferation. The OKT3 antibody shows potent immunosuppressive properties in vivo and has been proved effective in the treatment of renal, heart, and liver allograft rejection.
