Figure 7. Confirmation of phenotypic knockout of PD-L1.
Mouse peripheral blood mononuclear cells (PBMCs) were stimulated overnight with 10 ng/mL IFNγ and consequently surface-stained for PD-L1. (A) Gating strategy. (B) Representative overlay of histograms of PD-L1 expression of CD45+ immune cells as gated in A), showing PD-L1-/- cells in black (-/-) and wildtype cells in red (+/+).
