Fig. 3. (A) Measurement of the Cy3 counts generated by different concentrations of hOGG1. The inset shows the linear relationship between the Cy3 counts and the logarithm of the hOGG1 concentration. The Cy3-labeled molecular beacon (0.3 μM) and APE1 (0.1 U μL^–1) were used in this research. (B) Measurement of the Cy5 counts generated by different concentrations of hAAG. The inset shows the linear relationship between the Cy5 counts and the logarithm of the hAAG concentration. The Cy5-labeled molecular beacon (0.3 μM) and APE1 (0.1 U μL^–1) were used in this research. The error bars represent the standard deviations of the three experiments.
