• 

  FC experiment of human PBMCs using 65569-1-MR (same clone as 65569-1-PBS)

  1x10^6 human PBMCs were surface stained with 0.25 ug Anti-Human CD3 Mouse Recombinant Antibody (65569-1-MR, Clone: OKT3) or Mouse IgG2a Isotype Control (65208-1-Ig, Clone: C1.18.4), and CoraLite®488-Conjugated AffiniPure Goat Anti-Mouse IgG(H+L). Cells were then stained with CoraLite® Plus 405 Anti-Human CD19. Cells were not fixed. Lymphocytes were gated. This data was developed using the same antibody clone with 65569-1-PBS in a different storage buffer formulation.

  FC experiment of human PBMCs using 65569-1-PBS

  1x10^6 human PBMCs were surface stained with 0.5 ug Anti-Human CD3 (OKT3) Mouse IgG2a Recombinant Antibody, PBS Only (65569-1-PBS, Clone: OKT3) or Mouse IgG2a Isotype Control (C1.18.4) (65208-1-Ig, Clone: C1.18.4), and CoraLite®488-Conjugated AffiniPure Goat Anti-Mouse IgG(H+L) (SA00013-1). Cells were then stained with FITC Plus Anti-Human CD19. 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).
