Figure 2

Confocal fluorescence images of coucage and Cu2+ in MCF-7 cells; each panel shows an independent view from the same well. a) Bright-field transmission image. b) Cells incubated with 5 μM coucage for 20 min. c) Image taken 20 min after addition of 25 equiv of Cu2+ to coumarin-incubated sample. d) Image taken after 4 min of UV light exposure to coumarin/Cu2+-treated sample. Bar graph represents the average, background-corrected intensity from 10 randomly selected fields of view collected for each condition.
