Ionic effects on the elasticity of single DNA molecules

We used a force-measuring laser tweezers apparatus to determine the elastic properties of λ-bacteriophage DNA as a function of ionic strength and in the presence of multivalent cations. The electrostatic contribution to the persistence length P varied as the inverse of the ionic strength in monovale...
