活性（Bioactivity）-FACS
Flow cytometric analysis of Human peripheral blood lymphocytes respectively staining with APC-CY7-Labeled Monoclonal Anti-Human CD8 Antibody Mouse IgG1 (Cat. No. FABm003-05) at 1:20 dilution (5 μL of the antibody stock solution corresponds to labeling of 2.5e5 cells in a final volume of 100 µL), compared with isotype control antibody. APC-CY7 signal was used to evaluate the binding activity (QC tested).

背景
CD8a is a 32-34 kD type I glycoprotein. It forms a homodimer (CD8a/a) or heterodimer (CD8a/b) with CD8b. CD8, also known as T8 and Leu2, is a member of the immunoglobulin superfamily found on the majority of thymocytes, a subset of peripheral blood T cells, and NK cells (which express almost exclusively CD8a homodimers). CD8 acts as a co-receptor with MHC class I-restricted T cell receptors in antigen recognition and T cell activation and has been shown to play a role in thymic differentiation. Two domains in CD8a are important for function: the extracellular IgSF domain binds the α3 domain of MHC class I and the cytoplasmic CXCP motif binds the tyrosine kinase p56 Lck.
