摘要：
Interaction of a steroid drug, Ractopamine (RAC), and DNA was investigated by electroanalysis-differential pulse and cyclic voltammetry (DPV and CV), and UV-vis and fluorescence spectroscopy. DPV showed that RAC intercalated with DNA, and CV indicated that the reaction mechanism of RAC and dsDNA involved irreversible oxidation with the loss of two H(+) and a transfer of two electrons. Reaction binding parameters were obtained. Pure spectra of RAC, DNA and the RAC-DNA complex, and their concentrations were extracted by multivariate curve resolution-alternating least squares method (MCR-ALS). Concentration profiles indicated quantitatively the course of the reaction.
