Methods The human pancreatic cancer Panc-1 cells were exposed to a single fraction of high-doseγ-ray radiation either with CMNa or under hypoxic condition. The percentage of dead cells was detected with a multiwell plated reader, and fluorescence intensities of propidium iodide were measured before and after digitonin treatment.
