Delayed DNA double strand break repair in A-T cells assessed by the neutral comet assay. Note return to baseline (i.e. no comets) of WT at 2.5 hrs. Some comets remained at 3.5 hours for A-T cells. (A) The representative comet tails for each time point, in WT and A-T cells, post-10 Gy IR. (B) The quantitation of comet tail length for WT (white column) and A-T cells (gray column). Each data point refers to the average for at least 50 comets and the error bars represent standard errors.
