Questions? Please consult our answers to frequently asked questions at http://www.ebioscience.com/faq. DescriptionThe 53-6.7 monoclonal antibody reacts with the mouse CD8a molecule. CD8a is 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 αβ TCR T cells express CD8 αβ while γδ TCR T cells, a subpopulation of intestinal intraepithelial lymphocytes (IELs) and dendritic cells express CD8 αα. 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 ReportedFor research use only, not for diagnostic or therapeutic use. This 53-6.7 antibody has been reported for use in flow cytometric analysis. Applications TestedThis 53-6.7 antibody has been pre-titrated and tested by flow cytometric analysis of mouse splenocytes using eFluorTM NC Flow Cytometry Staining Buffer (cat. 00-3222). This can be used at 5 μl/test (one million cells in a 100μL total staining volume). The isotype control eFluorTM 605NC rat IgG2a (cat. 93-4321) should be used at 5 μl/test. Laser/Filter Recommendation: When using eFluorTM 605NC, we recommend excitation with the 405nm violet laser with an appropriate filter set, such as the 595LP dichroic mirror with the 605/40 bandpass filter. An acceptable alternative is the 610/20 bandpass filter. Please contact eBioscience Technical Support for more information. Buffer Recommendation: Comparison of eFluorTM Nanocrystal conjugated antibody staining in different buffers has demonstrated that optimal performance is seen with the eFluorTM NC Flow Cytometry Staining Buffer (cat. 00-3222). For a comparison of staining with different buffers, click here. Whole Blood Recommendation: If staining whole blood samples, collection into heparin or sodium citrate-containing tubes is recommended. If EDTA is being used as an anti-coagulant, lysis of RBCs with eBioscience 1X RBC Lysis Buffer (cat. 00-4333) before staining is required.
