Analyzing Cell Cycle Checkpoints After Ionizing Radiation

Several methods to measure cell cycle perturbation after exposure to ionizing radiation are presented in this chapter. These methods include the G1 checkpoint assay by 5′ bromode-oxyuridine (BrdUrd) labeling followed by flow cytometric analysis, the S-phase checkpoint assay by measuring DNA synthesis in response to ionizing radiation, and the G2/M checkpoint assay by quantitating histone H3 phosphorylation after ionizing radiation.
