Comparison of Scatchard and Klotz methods for Metal(II) -DNA complexes in the case two type of binding

TL;DR

This paper compares the Scatchard and Klotz methods for analyzing metal ion-DNA binding, highlighting that modified Scatchard plots provide a more realistic depiction of binding interactions.

Contribution

It demonstrates the effectiveness of modified Scatchard plots over Klotz methods in determining binding constants for two classes of metal-DNA complexes.

Findings

Modified Scatchard plots yield more realistic binding models.

Both methods can determine binding constants for two classes of sites.

Scatchard plots provide a better representation of the binding interactions.

Abstract

It was shown, that modified Scatchard plots and Klotz properties of graphical representations of two classes of binding sites could be used to determine binding constants of metal ion to DNA. More realistic picture is obtained by Scatchard plots.
