Fig. 4. Fluorescence images of ANRP (5 μM) in HepG2 cells under different conditions. Cells cultured with ANRP only, or pretreated with LPS (1 μg mL–1) for 24 h, 20 μM heme for 8 h, 800 μM APAP for 12 h, 800 μM APAP and 10 μM ZnPP for 12 h, then ANRP at 37 °C for 30 min. (b) The relative fluorescence intensities of the HepG2 cell membranes in panel (a). λex = 543 nm, λem = 600–700 nm.
