Background
CD4 is an Immunoglobulin Superfamily protein and an accessory protein for MHC class-II antigen/ T-cell receptor interaction. It may regulate T-cell activation. It plays a more general role in mediating cell recognition events than merely those of cellular immune response. The T4 molecule serves as a receptor for the human immunodeficiency virus. A Type I membrane protein, it is expressed on T lymphocytes, B-cells, macrophages, and granulocytes. It is also expressed in a developmentally regulated manner in specific regions of the brain. |
Antigen
PHA-stimulated human PBMC. |
Application Notes
RPA-T4 is capable of blocking HIV-1, gp120, and inhibits syncytium formation. The RPA-T4 clone reacts with CD4, a 59 kDa single-chain transmembrane glycoprotein [receptor for human HIV virus] present on T-helper/inducer cell populations. This antibody binds to the D1 domain of CDR1 and CDR3 epitopes. The CD4 antigen and reacts with approvimately 80% of thymocytes and 45% of peripheral blood lymphocytes. CD4 is also present in low density on peripheral blood monocytes.Clone RPA-T4 is widely published in literature, see Knapp W, Dorken B, Rieber E P, et all, ed. Also see Schlossman SF, Boumsell L, Gilks W, et al, ed. |

Cell surface flow cytometric analysis of CD4 in 1x106 human PBMC using 10 ul (0.1 ug) of IMG-5916G. Green represents isotype control (IMGENEX, 20107); red represents anti-CD4 antibody. Imgenex's cell surface staining flow assay kit (IMGENEX, 10084K) was used to test this product. Propidium iodide negative lymphocyte population gated for analysis. |
