Flow cytometric analysis of mouse primary splenocytes labeling CD8α (Alexa Fluor® 488 Conjugate) antibody at 1/200 (1 μg) dilution / (right panel) compared with a Rabbit IgG, Isotype Control / (left panel). Cells were surface stained with CD4-Alexa Fluor® 647, then stained with Rabbit IgG (Left) / CD8α (Right) separately. CD4 and CD8α are mutually exclusive expressed in mouse primary splenocytes. 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.

Immunofluorescence
IF shows positive staining in paraffin-embedded mouse thymus. Anti-CD8α (Alexa Fluor® 488 Conjugate) antibody was used at 1/200 dilution (Green). Counterstained with DAPI (Blue). Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
