Scientific Data

Immunocytochemistry CD4 antibody in Human T Cells by Immunocytochemistry (ICC). View Larger

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.

Immunocytochemistry CD4 antibody in Human PBMCs by Immunocytochemistry (ICC). View Larger

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; NL001) and counterstained with DAPI (blue). View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Immunohistochemistry CD4 antibody in Human Tonsil Tissue by Immunohistochemistry (IHC-P). View Larger

CD4 in Human Tonsil Tissue. CD4 was detected in immersion fixed paraffin-embedded sections of human tonsil tissue using Goat Anti-Human CD4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-379-NA) at 1.7 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (VC004). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cell surface of lymphocytes. Staining was performed using our IHC Staining with VisUCyte HRP Polymer Detection Reagents protocol.

Western Blot View Larger

Detection of Human CD4 by Western Blot. Western blot shows lysates of PBMC and SUP‑T1 human T cell lymphoblastic lymphoma cells. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human CD4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-379-NA) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for CD4 at approximately ~55kDa kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Simple Western View Larger

Detection of Human CD4 by Simple WesternTM. Simple Western lane view shows lysates of Human PBMC and SUP‑T1 human T cell lymphoblastic lymphoma cell line, loaded at 0.2 mg/mL. A specific band was detected for CD4 at approximately 65 kDa (as indicated) using 10 µg/mL of Goat Anti-Human CD4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-379-NA). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

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) 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.
