Cellular Reference Materials for DNA Damage Using Electrochemical Oxidation

Figure 6

Comparison of comet analyses by median and means averages of % DNA in tail. (a) Plot of average of the comet assay medians as a function of increasing treatment level. Each data point at a given treatment level is the average of the medians of 3 independent comet distributions (histograms shown in Supplementary Figure S2). Error bars represent the standard deviation of the medians at each treatment level. (b) Plot of average of the comet assay means as a function of increasing treatment level. Each data point at a given treatment level is the average of the means of the same 3 independent comet distributions (histograms shown in Supplementary Figure S2). The vertical error bars represent the standard deviation of the medians or means at each treatment level. The horizontal error bars represent the small instrument uncertainty in the applied potential.
