Research on ionizing radiation (IR)-induced clonogenic cell death is important for understanding the effects of IR on malignant tumors and normal tissues. Here, we describe a one-step assay for assessing the major modes of IR-induced clonogenic cell death based on morphology of 4',6-diamidino-2-phenylindole dihydrochloride (DAPI)-stained nuclei visualized by fluorescence microscopy.
