Effect of GO and S-rGO on LDH leakage in PMEF cells. LDH leakage was measured by changes in optical densities due to NAD+ reduction which were monitored at 490 nm, as described in the ‘Methods’ section, using cytotoxicity detection lactate dehydrogenase kit. The results represent the means of three separate experiments, and error bars represent the standard error of the mean. GO-treated groups showed statistically significant differences from the control group by Student’s t test (p < 0.05).
