活性（Bioactivity）-FACS
Flow cytometric analysis of Human peripheral blood lymphocytes respectively staining with PE-CY7-Labeled Anti-Human CD4 Antibody Mouse IgG1 (Cat. No. FABm002-04) 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. PE-CY7 signal was used to evaluate the binding activity (QC tested).

背景
T-cell surface glycoprotein CD4 is also known as T-cell surface antigen T4/Leu-3. CD4 contains three Ig-like C2-type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain. CD4 is accessory protein for MHC class-II antigen/T-cell receptor interaction. CD4 induces the aggregation of lipid rafts. CD4 is a primary receptor used by HIV-1 to gain entry into host T cells. HIV infection leads to a progressive reduction of the number of T cells possessing CD4 receptors. Therefore, medical professionals refer to the CD4 count to decide when to begin treatment for HIV-infected patients.
