Applications/Dilutions

Dilutions
  • Flow Cytometry 1ul/1 million cells
Application Notes
RPA-T4 is capable of blocking HIV-1, gp120, and inhibits syncytium formation. The RPA-T4 clone reacts with CD4, a 59 kDa single-chain transmembrane glycoprotein [receptor for human HIV virus] present on T-helper/inducer cell populations. This antibody binds to the D1 domain of CDR1 and CDR3 epitopes. The CD4 antigen and reacts with approvimately 80% of thymocytes and 45% of peripheral blood lymphocytes. CD4 is also present in low density on peripheral blood monocytes. Clone RPA-T4 is widely published in literature, see Knapp W, Dorken B, Rieber E P, et all, ed. Also see Schlossman SF, Boumsell L, Gilks W, et al, ed.

Background

CD4 is an Immunoglobulin Superfamily protein and an accessory protein for MHC class-II antigen/ T-cell receptor interaction. It may regulate T-cell activation. It plays a more general role in mediating cell recognition events than merely those of cellular immune response. The T4 molecule serves as a receptor for the human immunodeficiency virus. A Type I membrane protein, it is expressed on T lymphocytes, B-cells, macrophages, and granulocytes. It is also expressed in a developmentally regulated manner in specific regions of the brain.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.

  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.
