• 

  FC experiment of human PBMCs using CR-65133

  1X10^6 human PBMCs were surface co-stained with FITC Anti-Human CD19 and 5 ul Cardinal Red™ Anti-Human CD3 (CR-65133, Clone:OKT3) or Mouse IgG2a Isotype Control. Cells were not fixed. Lymphocytes were gated.

Background Information

CD3 is a multimeric protein associated with the T-cell receptor (TCR) to form a complex involved in antigen recognition and signal transduction (PMID: 15885124). CD3 is composed of CD3γ, δ, ε, and ζ chains (PMID: 1826255). It is expressed by thymocytes in a developmentally regulated manner, T cells, and some NK cells (PMID: 3289580). The TCR recognizes antigens bound to major histocompatibility complex (MHC) molecules. TCR-mediated peptide-MHC recognition is transmitted to the CD3 complex, leading to the intracellular signal transduction (PMID: 11985657).
