Background: CD8 is a co-receptor for the T cell receptor (TCR) and is expressed on cytotoxic T cells.  Cortical thymocytes, dendritic cells and NK cells can also express CD8. CD8 binds to MHC Class I to aid in antigen recognition and TCR-mediated activation. CD8 forms dimers of CD8ɑ and CD8β and clone C8/144B recognizes the alpha form of CD8.

Validation: Each lot of conjugated CD8 antibody is quality control tested by MIBIscope™ analysis of stained tissue microarrays using the appropriate positive and negative tissue field of views and are pathologist verified.

Recommended Usage: 1 uL of CD8 antibody per 100 uL staining volume using the MIBI™ Staining Protocol.
For optimal results, antibody should be titrated for each desired application.  Suggested starting range is 1:100.
