Comet analysis of the CHO-K1 hamster ovary cells presenting control cells (no treatment), the anthracenes alone (Ant-PIm, Ant-PHEA), light alone (30 s), and PDT-based anthracene (ANT-PIm + Light (30 s), Ant-PHEA + Light (30 s), both 2.5 µM, 24 h). The comet assay was performed immediately after light exposure, as described in the “Materials and Methods”. The data are one representative experiment out of three independent runs. Mean ± SD, n = 100.
