The Anti-Human CD3-APC/CD4-FITC/CD8a-PE Cocktail is a comprehensive tool for flow cytometry analysis of T cell populations in human samples. This cocktail contains antibodies that specifically target CD3, CD4, and CD8a markers, allowing for precise identification and characterization of T cell subsets.The CD3 marker is a key component of the T cell receptor complex, while CD4 and CD8a are important for distinguishing between helper T cells and cytotoxic T cells, respectively. By using this cocktail, researchers can analyze the distribution and function of different T cell subsets in various immune responses, including infections, autoimmunity, and cancer.
This cocktail is ideal for studying T cell biology in immunology research and clinical diagnostics. It provides a convenient and reliable tool for identifying and quantifying T cell populations in human samples, ultimately leading to a better understanding of immune responses and potential therapeutic strategies.

Recommended Use:
For whole blood samples, add 5 μL Anti-Human CD3-APC/CD4-FITC/CD8a-PE Cocktail to 100 μL anticoagulant- treated blood sample. Mix and incubate the sample at 4°C in the dark for 30 min. Remove red blood cells with RBC lysis solution following the manufacturer's instruction. Wash the cell with cell staining buffer and discard the supernatant after centrifugation at 300 g for 5 min. Resuspend the cells with 200 μL cell staining buffer and load the sample on flow cytometer for detection. For other samples, 1×106 dissociated single cells are centrifuged at 300 g for 5 min with the supernatant discarded. Resuspend the cells with 100 μL cell staining buffer and add 5 μL Anti-Human CD3-APC/CD4-FITC/CD8a-PE Cocktail. Mix and incubate the sample at 4°C in the dark for 30 min. Add cell staining buffer to each tube, centrifuge at 300 g for 5 min and discard the supernatant. Resuspend the cells with 200 μL cell staining buffer and load the sample on flow cytometer for detection.

Background:
This product is a FCM antibody cocktail made up of APC Anti-Human CD3 Antibody [Clone: OKT-3] (Mouse IgG2a, κ), FITC Anti-Human CD4 Antibody [Clone: RPA-T4] (Mouse IgG1, κ) and PE Anti-Human CD8a Antibody [Clone: OKT-8] (Mouse IgG2a, 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.
