Figures 2: A-C show the response of the two normal lymphoblastoid cell lines to increasing doses of gamma radiation in the presence and absence of 5 μM Olaparib. The GM00893 cell line is shown in Figure 2A and the GM05432 cell line is shown in figure 2B. Figure 2C combines two normal cell lines into a single survival curve. Broken lines show the response of the cells to gamma radiation alone while the unbroken line shows the response to gamma radiation in the presence of Olaparib. Error bars represent standard error of the mean of at least three independent experiments.
