Fig. 3. Fluorescence imaging (a) and quantification (b) of RAW264.7 cells with GSH-PF3 (10 μM) in the absence and presence of exogenously added GSH (50 μM) and/or SIN-1 (500 μM). Excitation channel = 460–490 nm, emission channel filtered = 530–590 nm. Cell nuclei were stained with Hoechst 33342. Scale bar = 100 μm. Error bars represent SD.
