Visualization of enzyme activity and membrane integrity with FDA–PI double-staining. Cells were irradiated with X-ray or CI radiation and stained using FDA–PI, as described in Materials and Methods. A (X-ray) and B (CI) represent X-ray and CI radiation exposure, respectively. Left panel: fluorescence micrographs of incorporated FDA and PI. Right panel: phase contrast micrographs of the same cells. Scale is 20 μm.
