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.
The photo-emission properties and compensation required for Alexa Fluor® 750 are similar to APC-Cy7; however Alexa Fluor® 750 has several advantages when compared to APC-Cy7. The Alexa Fluor® 750 has peak emission of 779 nm, and usually has a slightly higher mean fluorescent intensity when compared to the same clone conjugated with APC-Cy7, which has peak emission of 767 nm. Furthermore, Alexa Fluor® 750 is considered to be a more photostable fluorochrome as compared with APC-Cy7. It is advised not to use fixatives with Alexa Fluor® 750 as this may lead to degradation of the fluorochrome and loss of staining.
Applications Tested
This 53-6.7 antibody has been tested by flow cytometric analysis of mouse thymocyte and splenocyte suspensions. This can be used at less than or equal to 0.5 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
