背景 | 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) residue precursor protein with a 25 aa residue signal peptide, a 371 aa residue extracellular region containing four immunoglobulin homology domains, a 24 aa residue transmembrane domain and a 38 aa residue 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. |

CD4 in Human T Cells. CD4 was detected in immersion fixed human T cells using 2 µg/mL Goat Anti-Human CD4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF‑379‑NA) for 3 hours at room temperature. Cells were stained (red) and counterstained (green). View our protocol for Fluorescent ICC Staining of Cells on Coverslips. | |
CD4 in Human PBMCs. CD4 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Goat Anti-Human CD4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-379-NA) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (yellow; Catalog # NL001) and counterstained with DAPI (blue).
