Background Information
CD4 is a 55-kDa transmembrane glycoprotein expressed on T helper cells, majority of thymocytes, monocytes, macrophages, and dendritic cells (PMID: 9304802; 12213222). CD4 is an accessory protein for MHC class-II antigen/T-cell receptor interaction. It plays an important role in T helper cell development and activation (PMID: 9539765; 3112582). CD4 serves as a receptor for the human immunodeficiency virus (HIV) (PMID: 9304802).

Jianhua (Verified Customer) (07-02-2026) | Great antibody for flow cytometry assays in human T cells!
|
Ariana (Verified Customer) (07-01-2025) | Amazing product! The cell populations are well discriminated even when I tested at low concentration of antibody. At high concentrations the discrimination is better and the negative populations remain on the zero. Definitely recommend.
