a A549, HeLa, KYSE–150 and 293T cells incubated with CB[8]/HA–BrBP ([BrBP] = 25 µM, [CB[8]] = 12.5 µM). b A549 cells incubated with HA–BrBP ([BrBP] = 25 µM). c A549 cells incubated with CB[8]/HA–BrBP ([BrBP] = 25 µM, [CB[8]] = 12.5 µM). 4, 6–Diamidino–2–phenylindole (DAPI, blue) was used to stain the nuclei, and MitoTracker (red) was used to stain the mitochondria.
