Kinetics of γ-H2AX foci in G1, S and G2 cells irradiated with γ-rays.

<p>(A) Values of γ-H2AX foci FI are mean ± S.D. from SOID determinations carried out in at least four independent experiments in cells irradiated with 0.5 and 5Gy. (B) Disappearance of γ-H2AX foci FI in G1- and G2-phases cells calculated in the 0.5–6h and 6–24h time-windows after irradiation (*<i>P</i><0.05, **<i>P</i><0.01, G2 cells vs. G1 cells, <i>t</i>-test).
