Figure 2From: Survival of tumor cells after proton irradiation with ultra-high dose ratesAccumulation of cells in G2 phase after irradiation. Cells were irradiated with protons (3 Gy) in pulsed mode (P) or continuous mode (C). Data are from 3 independent experiments, except for irradiated (3 Gy) sample at 0 h (1 experiment). Indicated are means and standard errors of the mean (SEM).Back to article page
