Fig. 6. Fluorescence microscopic analyses of 2 (10 μM) in HeLa cells co-incubated with Lysotracker® Red DND-99 (50 nM, Ex: 543 nm; Em: 565–615 nm) (top), Mitotracker (50 nM, Ex: 543 nm; Em: 565–615 nm) (middle) or Hoechst 33342 (1 μM Ex: 800 nm [two photon]; Em: 435–485 nm) (bottom). The 2 (green) and 2 (orange) are both excited at 458 nm but with emission channels of 500–550 nm and 650–700 nm, respectively.
