title: Polyelectrolyte effects on 9-aminoacridine-DNA binding.
abstract: The 9-aminoacridine-DNA binding curve is analyzed in two ways: with polyelectrolyte effects neglected and with polyelectrolyte effects included. It is found that the analysis which includes polyelectrolyte effects is consistent with the violation of neighbor exclusion displayed by diacridine complexes as observed by Atwell et al. and by Zimmerman and coworkers. However the analysis which neglects polyelectrolyte effects is inconsistent with the diacridine results. This comparison supports the necessity of including polyelectrolyte effects in the analysis of drug-DNA binding curves.
