Figure 3: Comet assay images. Images of comet assay results of IOSE-29cells. As expected, treatment with bleomycin resulted in larger comet tails,signifying greater DNA damage. Treatment with norepinephrine resulted in lesstail, and subsequent treatment with norepinephrine after treatment with DNAdamaging agent resulted in smaller tail. Bleo: Bleomycin; NE: Norepinephrine;Bleo->NE: 30 minute treatment with bleomycin followed by 30 minute treatmentwith norepinephrine.
