Figure 1 van’t Hoff plot of DAPI:DNA binding in 0.10M salt. The symbols represent data points calculated according to the procedure described in the text; the dotted lines are the results of a linear fit to the integrated van’t Hoff equation. (♦) ΔCpel, varying both Boltzmann and dielectric factors; (■) ΔCpions, Boltzmann factor kept constant; (•) ΔCpwater, dielectric held constant.
