特徴

• 背景：This product is a FCM antibody cocktail made up of APC Anti-Human CD3 Antibody [Clone: OKT3] (Mouse IgG2a, kappa ), FITC Anti-Human CD4 Antibody [Clone: RPA-T4] (Mouse IgG1, kappa ) and PE/Cyanine5.5 Anti-Human CD8a Antibody [Clone: OKT-8] (Mouse IgG2a, kappa ).CD3 is a heterotetrameric protein consisting of a CD3 gamma , a CD delta and 2 CD3 epsilon . It forms complex with TCR. OKT-3 recognize human CD3 epsilon . Human CD3 is expressed on the surface of T cells and NKT cells.CD4 is also called Leu-3 or T4. It's a single-chain type I transmembrane glycoprotein, mainly expressed on the surface of T cells, and monocytes/macrophages. In T cells, CD4 forms complex with TCR/CD3 and play important roles in T cell immunity. The target of HIV is CD4+ T cells. Reduction of CD4+ T cells is the main reason of defected immunity after HIV infection.CD8 is mainly expressed on cytotoxic T cells and also some subpopulations of NK cells. CD8 forms dimer function. In most cells, CD8 is a heterodimer consisting of CD8a and CD8b, but in NK cells nearly all CD8 is homodimer of CD8a. CD8a can form co-receptor with MHC-I restricted TCR to promote T cell antigen recognition and activation.
