CD4 in Human PBMCs. CD4 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Mouse Anti-Human CD4 Monoclonal Antibody (Catalog # MAB379) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 493-conjugated Anti-Mouse IgG Secondary Antibody (green; Catalog # NL009) and counterstained with DAPI(blue). Specific staining was localized to the cell surface. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Detection of Human CD4 by Immunocytochemistry/Immunofluorescence CX3CR1 expressions in affected muscle of patients with polymyositis. The muscle tissues of polymyositis (PM) patients were double-stained with CD4, CD8, or CD68, as well as CX3CR1, and were analyzed with fluorescent microscopy: (A) CX3CR1, (B) CD4, (C) merged (A) and (B), (D) CX3CR1, (E) CD8, (F) merged (D) and (E), (G) CX3CR1, (H) CD68, and (I) merged (G) and (H). Arrows indicate double-positive cells. Original magnification, ×400.

Background: CD4

CD4 is an approximately 55 kDa type I membrane glycoprotein that is expressed predominantly on most thymocytes and a subset of mature T lymphocytes. In humans, CD4 is also expressed to a lesser extent on monocytes and macrophage related cells. Human CD4 cDNA encodes a 458 amino acid (aa) precursor protein with a 25 aa signal peptide, a 371 aa extracellular region containing four immunoglobulin homology domains, a 24 aa transmembrane domain and a 38 aa cytoplasmic domain. CD4 is a coreceptor required for T cell recognition of antigens that are presented by class II major histocompatibility complexes. CD4 has been shown to be a coreceptor of HIV entry and specifically binds gp120, the external envelope glycoprotein of HIV.
