Cellular Reference Materials for DNA Damage Using Electrochemical Oxidation

Figure 2

Fluorescent microscope images of the Live/Dead assay before (a) and after (b) the electrochemical treatment for 12 h at V. The intracellular esterase activity by live cells is shown by the green fluorescent calcein dye. The loss of plasma membrane integrity of dead cells is shown by the red fluorescent ethidium homodimer. The calculated percentage of live cells before and after the electrochemical treatment is given in Table 1.
