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.

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 antibod

Cell surface flow cytometric analysis of CD4 in 1x106 human PBMC using 10 ul (0.1 ug) of IMG-5916D. Green represents isotype control (IMGENEX, 20106); 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.
