Figure 5: Sensitivity of HR-deficient CHO cells to anticancer agents and X-rays. AA8 (wild type, open circle) and 51D1 (deficient in RAD51D, closed circle) cells were treated with cisPt (A), azadC (B), MMC (C), or X-rays (D). The treated cells were further incubated in fresh medium for 6 days, and colonies were scored to calculate the surviving fraction. The data points are the average from two experiments.
