- Description
| Specificity Profile | More Information |
 | The specificity of CD4 Monoclonal Antibody (CSB0118) was tested on the Membrane Proteome Array™ and shown to be specific for human CD4. The Membrane Proteome Array™ contains 6,000 different human membrane proteins, each expressed in unfixed human cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array™ represents the industry standard for determining the binding specificity of antibodies and other protein ligands. |
| Application | Conditions | Recommended Concentration |
| Flow Cytometry, Extracellular | Live, Unpermeabilized | 1 µg/ml |
 | HEK-293F cells transiently transfected with human CD4 were stained with CD4 Monoclonal Antibody (CSB0118) (green) or isotype control antibody (gray), followed by AlexaFluor 647-conjugated anti-Mouse IgG secondary antibody. HEK-293F cells transiently transfected with an empty control vector were also stained with CD4 Monoclonal Antibody (CSB0118) (blue). | |

CD4 is a single-pass transmembrane protein and integral membrane glycoprotein. CD4 is a coreceptor with the T-cell receptor and is involved in recognition of antigens and T-cell activation. CD4 is a receptor for HIV-1 and Human Herpes virus 7 and may be involved in infectious and immune-mediated central nervous system diseases. (NCBI Gene: 920, UniProtKB/Swiss-Prot: P01730). Other names: CD4mut, IMD79, OKT4D, T-Cell Surface Antigen T4/Leu-3
