The characterization of DNA damage by comet assay. (A) Comet assay conducted on HeLa and A549 cells exposed to 6 Gy irradiation in the presence of 1P (10 μmol/L) or 1P + ALP. Scale bar = 20 μm. Inserts: representative tail DNA image obtained from comet assay software project (CASP). (B) Tailed DNA percentages in HeLa and A549 cells exposed to 6 Gy irradiation in the presence of 1P or 1P + ALP (Data are expressed as mean ± SD, n = 40; ∗P < 0.05, ∗∗∗P < 0.001).
