Flow cytometric analysis of C57BL/6 mouse splenocytes labelling Mouse CD8α antibody at 1/20000 (0.001 μg) dilution (Right) compared with a Rat monoclonal IgG isotype control (Left). Goat Anti - Rat IgG Alexa Fluor® 488 was used as the secondary antibody. Then cells were stained with CD4 - Alexa Fluor® 647 separately. Gated on total viable cells.

Background
CD8α encodes the CD8 alpha chain of the αβT cells, proposed as a quantifiable indicator for CD8+ CTL recruitment or activity assessments and a robust biomarker for responses to anti-PD-1/PD-L1 therapy. In NK-cells, the presence of CD8A homodimers at the cell surface provides a survival mechanism allowing conjugation and lysis of multiple target cells. CD8A homodimer molecules also promote the survival and differentiation of activated lymphocytes into memory CD8 T-cells.
