Background | This product is a FCM antibody cocktail made up of FITC Anti-Human CD3 Antibody [Clone: OKT-3] (Mouse IgG2a, κ),PE Anti-Human CD4 Antibody [Clone: RPA-T4] (Mouse IgG1, κ), PE/Cyanine7 Anti-Human CD8a Antibody[Clone: OKT-8] (Mouse IgG2a, κ) and PerCP Anti-Human CD45 Antibody [Clone: HI30] (Mouse IgG1, κ).;
CD3 is a heterotetrameric protein consisting of a CD3γ, a CDδ and 2 CD3ε. It forms complex with TCR. OKT-3 recognize human CD3ε. 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.;
CD45 is a single-chain type I transmembrane glycoprotein. Except for erythrocytes and platelets, CD45 is expressed on nearly all of the hematopoietic cells with high level. It is a common marker for blood leukocytes. CD45 is a receptor type protein tyrosine phophatase and plays essential roles in B cell and T cells signaling. |

Q1:Are CD8 and CD8α the same index?
Yes they are. CD8 and CD8α are widely used markers for identifying cytotoxic T lymphocytes (CTLs). CD8 plays an important role in mediating the recognition and excution funtions of CTLs. CD8α is a subunit of CD8 complex, which means the α chain, and it is quite important in the formation of the complex. CD8α chain not only participates in the binding with MHC-I molecules, but also regulates the activity of CTLs by interacting with other signal molecules. Therefore, the expression level and functional status of CD8α can be used for evaluating the activation and effection of CTLs, as well as CD8.
