CD8β expression on CD8α⁺ αβ T cells in healthy individuals.

PBMNCs from healthy individuals and cord blood were stained with FITC-conjugated anti-TCRαβ, PE-conjugated anti-CD8β, and RPE-Cy5–conjugated anti-CD8α mAbs. TCRαβ and CD8α gated cells were analyzed for the expression of CD8α (y-axis) versus CD8β (x-axis). Representative data are displayed.
