Neutral comet assay measuring the effects of DNA damage 5 h after 15 Gy. Note that all but two radiosensitive LCLs (RS07, RS15) had “AT-like” reduced DNA repair efficiency. Error bars for all LCLs tested represent means ± SD of three experiments, normalized to the average tail moments of five different wild-type LCLs, WT1 to 5 (first bar). Inset 1: Representative data from WT1 and AT3 LCLs demonstrates the kinetics of tail moment 30 min and 5 h postirradiation. Tail moment on the y-axis is the measurement of pixel fluorescence in the form of arbitrary units. The tail moment values of the nonirradiated cells and cells 5 h postirradiation were used to calculate the average percentage return to baseline (%RTB) represented in the bar graph. Inset 2: Representative photomicrographs of comet tails (WT1 and RS18) at 5 h after damage.
