Description
The 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 Reported
For research use only, not for diagnostic or therapeutic use. This 53-6.7 antibody has been reported for use in flow cytometric analysis.
Applications Tested
This 53-6.7 antibody has been pre-titrated and tested by flow cytometric analysis of mouse splenocytes using eFluor 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 eFluor 605NC rat IgG2a (cat. 93-4321) should be used at 5 μl/test.

Laser/Filter Recommendation: When using eFluor 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. For instruments not equipped with a violet laser, the eFluor 605NC is also excited by the 488 nm blue laser and can be used as a PE-Texas Red alternative. Please contact eBioscience Technical Support for more information.

Buffer Recommendation: Comparison of eFluor Nanocrystal conjugated antibody staining in different buffers has demonstrated that optimal performance is seen with the eFluor NC Flow Cytometry Staining Buffer (cat. 00-3222). For a comparison of staining with different buffers, refer to eFluor® Nanocrystals page.

Fixation Recommendation: When fixing samples that have been stained with nanocrystal reagents, we recommend keeping the total volume at approximately 200 μl for fixation and the exposure time 30-60 minutes to preserve the optimal fluorescent signal from the nanocrystal reagent.

For answers to additional questions about fixation and other FAQs refer to eFluor® Nanocrystal Frequently Asked Questions.
