Abstract

The stability of noncovalent protein–DNA complexes is typically sensitive to the ionic composition of the solution, in a manner that is dependent on the specific ion concentrations and is not a simple ionic strength effect. One important origin of this sensitivity to solution conditions is the polyelectrolyte effect.
