Description
This product consists of two fluorochrome-conjugated monoclonal antibodies to distinguish human peripheral CD4
+ and CD8
+ T cells. The RPA-T4 monoclonal antibody (mouse IgG1, κ, HLDA #IVT114) 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). The RPA-T8 monoclonal antibody (mouse IgG1, κ, HLDA #IVT171) 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 product is formulated for use in two-color analysis by flow cytometric analysis.
Applications Tested
The reagent has been pre-titrated and tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at 20 μl per 100μl blood (or per 1 million cells in 100 μl total staining volume).
