Fig.3.3.1.6 Phosphorylation of Chk1 and Chk2 at 4h after exposure to 1Gy gamma or carbon<br />

irradiation in A549 cells. (A) Graph represents relative phosphorylation of Chk1 as determined<br />

by ImageJ software (B) Representative image showing phosphorylation and Chk2 foci (marked<br />

by “arrow”). The encircled area roughly represents cell nuclei as seen by DAPI staining. All<br />

images were captured using Carl Zeiss confocal microscope with the same exposure time (C)<br />

Graph represents relative phosphorylation of Chk2 as determined by ImageJ software. At least<br />

100 cells per experiment were analyzed from three independent experiments. Data represents<br />

means ± SD of three independent experiments.<br />
