Figure S1. 53BP1 focus formation in cells treated with NCS. Cells were transfected with scramble siRNA (si-Scr), CK2α or -α'-siRNA for 72 hours. Where indicated, 0.5 μg/ml neocarzinostatin (NCS) was added to the medium in the last 24 hours of incubation. Fixed cells were subsequently labeled with anti-53BP1 antibody and with a FITC-conjugated secondary antibody. Nuclei were visualized by DAPI staining.
