Title | The Electrophoretic Separation of Curved Cisplatin-Modifled DNA Fragments on Polyacrylamide Gels Is Dependent on the Voltage Gradient ![]() | ||
Abstract | Polyacrylamide gel electrophoresis has been widely used to study DNA fragments containing sequence-de-pendent curvature. The anomalous electrophoretic be havior of curved DNA fragments on such gels allows their separation from straight fragments of the same length. H ere we dem onstrate that polyacrylamide gels can be successfully used to resolve DNA fragments m od ified at a single site by the antitum or drug ds-diam-m inedichloroplatinum (II) (ds-DDP, cisplatin) from their unmodified counterparts. However, the resolution strongly depends on the voltage gradient, being com pletely lost when it drops below a certain threshold level. The param eters of the electric field do not affect separation of 'norm al' DNA fragments of comparable length. | ||
