Cancer Research One-step Protocol for Evaluation of the Mode of Radiation-induced Clonogenic Cell Death by Fluorescence Microscopy Daijiro Kobayashi1, Atsushi Shibata2, Takahiro Oike1, Takashi Nakano1 1Department of Radiation Oncology, Gunma University Graduate School of Medicine, 2Advanced Scientific Research Leaders Development Unit, Gunma University Graduate School of Medicine 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.
