Background

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.

Comments

CommentsPig spleen frozen OCT tissues were sectioned at 7µm and fixed in ice cold acetone for 7min. Once dry, blocking buffer 4% FCS/TBS was added to all tissues for 30min to minimize non-specific binding, followed by 10 min incubation with Bloxall, endogenous peroxidase blocking solution at room temperature. Tissues were washed in Tris buffered saline (TBS) for 5 min and incubated for 20min with normal horse serum (Vector laboratories # S-2012-50). Human Polyclonal goat anti-CD4 (Novus biologicals # AF379-NA) was diluted at 1:50 in 0.5% FCS/TBS and added to the arterial tissues for 1 hour incubation at room temperature. Following 5 min wash in TBS, tissues were incubated for 30min with ImmPRESS®HRP horse anti-goat reagent (Vector laboratories # MP-7405). To detect CD4 antigen, tissues were washed in TBS and incubated with VIP HRP substrate (Vector®VIP Substrate kit, Peroxidase (HRP) # SK-4600) for 1 min 30sec then placed immediately in MilliQ water to stop the reaction. Nuclei were counter-stained with methyl green (Sigma-Aldrich # M8884-25G). Control tissues were stained similarly in the absence of the primary antibody. Tissue sections were immediately dehydrated and mounted with ENTELLAN mounting medium (Proscitech, Cat#IA013). Images were captured on Nikon eclipse ME600 microscope and DS-Fi2 camera.

FAQs for CD4 Antibody (AF-379-NA). (Showing 1 - 1 of 1 FAQs).

  1. I want to stain some T cell subsets (Th17 and Th1), do you have antibodies for that? I need for flow cytometer in sheep or goat.
    • Unfortunately, we have neither a CD4 antibody nor an IL-17 antibody that has been validated in sheep or goat, although if you would like to try one you would again be eligible for our Innovators Reward Program.
