Figure 1. Measurement of high concentrations of DNA (0-20 μg/ml)
The graphs show the observed data with the linear regression models for the relationship between DNA concentration and observed fluorescence enhancement. Statistical analysis confirms the validity of each model and suggests that ethidium bromide can distinguish smaller differences in DNA concentration than Hoechst 33258 in this range (Table 2A). A: Ethidium bromide. B: Hoechst 33258.
