title: [Study of complexes of ethidium bromide with DNA by differential pulse voltammetry].
abstract: The interaction of ethidium bromide with calf thymus DNA was investigated by the method of differential pulse voltammetry. It was found that ethidium bromide binds with DNA in several ways. Corresponding values of the constants and the number of binding sites were determined. The intercalation, semi-intercalation, and electrostatic mechanisms of interaction were shown. The results obtained are in good agreement with the data obtained by spectroscopic (absorption and fluorimetric) methods.
