Description
This product consists of two fluorochrome-conjugated monoclonal antibodies to distinguish human peripheral CD3
+ and CD8a
+ T cells. The UCHT1 monoclonal antibody (mouse IgG1, κ, HLDA #III471) reacts with human CD3e, a 20 kDa subunit of the TCR complex. Along with the other CD3 subunits γ and δ, the ε chain is required for proper assembly, trafficking and surface expression of the TCR complex. CD3 is expressed by thymocytes in a developmentally regulated manner and by all mature T cells. 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 CD8b 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 lot 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).
