Description

The RPA-T4 monoclonal antibody reacts with human CD4, a 59 kDa cell surface receptor expressed by a majority of thymocytes, subpopulation of mature T cells (T-helper cells) and in low levels on monocytes. CD4 is a receptor for the human immunodeficiency virus (HIV). RPA-T4 blocks HIV binding and mixed lymphocyte reaction. The RPA-T4 antibody recognizes a different epitope than the OKT4 monoclonal antibody, and these antibodies do not cross-block binding to each other's respective epitopes.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The RPA-T4 antibody has been reported for use in flow cytometric analysis.

This tandem dye is sensitive to photo-induced oxidation. Protect this vial from light during storage and all handling steps. When staining cells with PE-Cy7-conjugated antibodies, always protect samples from light.

Applications Tested

The RPA-T4 antibody has been pre-titrated and tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at 20 μl (1μg) per 100 μl blood (or per 1 million cells in 100 μl total staining volume).
