Off-line coupling of automated pipetting system with square wave voltammetry as a tool for study of drug-DNA interaction
2010
Abstract
Manual handling with DNA and drugs can be a source of errors, which can be eliminated also by automation of whole process of sample preparation. The aim of this work was to study interaction between DNA and ellipticine by using of off-line coupled automated pipetting system with adsorptive transfer stripping technique (AdTS) square wave voltammetry (SWV).
Interaction between dsDNA and ellipticine was evident from the decrease of CA signal. Six ng of ellipticine per ml resulted in a statistically significant decrease in CA signal (the decrease was higher than the standard deviation of determinations, Student t-test).
The decrease in CA signal corresponded to increasing ellipticine concentrations.
