CD4 is an approximately 55 kDa type I transmembrane glycoprotein that is expressed predominantly on thymocytes and the Th1, Th2, Th17, Tfh, and Treg subsets of mature T lymphocytes. In human, CD4 is additionally expressed on macrophages, neutrophils, monocytes, NK cells, and neurons and glial cells in the brain. CD4 binding to MHC class II molecules on antigen presenting cells contributes to the formation of the immunological synapse. CD4 also functions as a chemotactic receptor for IL-16 and, in human, as a coreceptor for the gp120 surface glycoprotein of HIV-1.
This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed

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.
