Change in FluoZin-3 fluorescence intensity by NEM. a NEM-induced shift of FluoZin-3 fluorescence histogram. FluoZin-3 fluorescence was measured from cells that were not stained with propidium iodide. Each histogram was constructed with 2,500 cells. b Concentration-dependent augmentation of FluoZin-3 fluorescence by NEM. Columns and bars indicate means and standard deviations, respectively, of five experiments. ^## P < 0.01 significant difference compared with control
