Figure 2

Time-course kinetics of DNA repair-deficient LCLs. γH2AX foci per nucleus are shown for controls (n=11; open bars), homozygous ATM mutant (three experimental replicates; grey bars) and ligase IV knock-out (three experimental replicates; black bars) human cell lines. γH2AX foci number was counted in cells before (0 h) and 1 and 8 h after exposure to 2 Gy of IR. Error bars represent s.e.m. of γH2AX foci number per nucleus.
