From: Effect of prolonging radiation delivery time on retention of gammaH2AX

Figure 1

Comparison between surviving fraction and relative retention of γH2AX for SiHa cells exposed to 2 or 4 Gy over 0.5 or 1 min or protracted over 30 or 60 min. Panel a: Clonogenic surviving fraction (mean ± SD). Panel b: Residual γH2AX relative to unirradiated cells (mean ± SD). Panel c: Comparison between results in panel a and b. Linear best fits are shown for the acute and protracted exposures. Panel d: Relative γH2AX calculated for 3 independent experiments of 6 samples when SiHa cells were exposed to 2 Gy using the protracted protocol. Mean ± SD for the pooled samples is indicated by the lines. The F value is 18.95 indicating significant inter-experimental differences.
