(c) Confocal images showing the localization of free HPPH and BCCGH in the different organelles of A549 cells. Hoechst 33342 (Hoechst), ER-Tracker Green (ER-Tracker), rhodamine 123 (Rhod-123), LysoTracker Green (LysoTracker), Golgi-Tracker Green (Golgi-Tracker), and cholesterol-polyethylene glycol (PEG)2k-fluorescein isothiocyanate (Chol-PEG-FITC) were adopted to visualize the nucleus, ER, mitochondrion, lysosome, Golgi apparatus, and plasma membrane, respectively. Scale bar: 10 μm. (d) Confocal images of Hoechst- and FITC-labeled γ-H2AX-stained A549 cells after various treatments as indicated. Scale bar: 10 μm.
