Co-internalization of BODIPY–RNase A and OG–ONC in K-562, JAR, and HeLa cells. Cells were incubated with OG–ONC (green) or BODIPY–RNase A (red; 1 µM, 10% labeled) for 20 minutes at 4°C. After a 5-minute incubation at 37°C, cells were washed three times with ice-cold PBS and fixed; and their fluorescence was visualized directly.
