(A) Stains as a group of cells. (B) Stains of single cell. (C) HEK-293 cells stained for PD-L1 (red) and nuclei (blue). (D) HEK-293 cells transfected with PD-L1 stained for PD-L1 (red) and nuclei (blue). The images were taken using confocal microscopy. Scale bar, 10 μm. (E) Flow cytometric evaluation of intracellular PD-L1 expression vector control-transfected (left panel) and PD-L1–transfected (right panel) HEK-293 cells.
