Laser microirradiation was performed using 405 nm laser under the Zeiss Axiovert 200M Microscope with Marianas Software (Intelligent Imaging Innovations, Inc. Denver, CO, USA).
Settings for laser microirradiation: focus menu > photomanipulation; choose 405 nm laser, adjust power level, duration, raster block size. To aid the inital setting, we used GFP-Ku70, GFP-PARP1 and other DNA repair proteins as positive controls. Laser aliignment should be routinely checked (focus menu > align photomanipulation).
