Description

The RPA-T8 monoclonal antibody reacts with the human CD8a molecule, an approximately 32-34 kDa cell surface receptor expressed either as a heterodimer with the CD8 β chain (CD8 αβ) or as a homodimer (CD8 αα). A majority of thymocytes and a subpopulation of mature T cells and NK cells express CD8a. CD8 binds to MHC class I and through its association with protein tyrosine kinase p56lck plays a role in T-cell development and activation of mature T cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This RPA-T8 antibody has been reported for use in flow cytometric analysis.

Applications Tested

This RPA-T8 antibody has been pre-titrated and tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at 5 μl (0.25 μg) per 100 μl blood (or per 1 million cells in 100 μl total staining volume).
