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. The RPA-T8 antibody been reported for use in flow cytometric analysis.

Applications Tested

This RPA-T8 antibody is offered in 2 formats:

- μg size: has been tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at less than or equal to 0.125 μg per 100 μl blood (or per 1 million cells in 100 μl total staining volume). It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

- test size: has been pre-titrated and tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at 20 μl (0.125 μg) per 100 μl blood (or per 1 million cells in 100 μl total staining volume). The pre-titrated test size contains BSA and/or gelatin for protein stabilization.
