Figure 3. The results of γH2AX foci formation assay after 1.8 GHz microwave treatment. A: The percentage of γH2AX positive cells is shown. No significant changes of DSBs were detected after exposure to the 3 W/kg and 4 W/kg radiation. B: Images of γH2AX foci is shown. The nuclei stained by DAPI exhibit in blue, while the DSBs stained by FITC exhibit in green. The asterisk indicates that p<0.001
