Image samples obtained by the application of the yeast comet assay for untreated cells (0 Gy) and cells treated with CI (A) or X-rays (B) radiation of 100 and 175 Gy. The images were acquired with fluorescence microscopy at ×400 magnification and correspond to a representative assay from 3 independent experiments. Here, the blue arrow represents the cells that did not form comets (ie, did not form protoplasts); white bar = 20 μm. CI indicates carbon ion.
