DiOC6 can be used to label living cells, however they are quickly damaged due to the dye's extreme phototoxicity, so cells stained with this dye can only be exposed to light for short periods of time. When exposed to blue light, the dye fluoresces green.
DiOC6 can be employed for cell labeling; however, it suffers from severe phototoxic effects that restrict light exposure duration. Upon exposure to blue light, DiOC6 exhibits green fluorescence.
