摘要: 采用循环伏安法(CV)和差示脉冲伏安法(DPV)研究了配合物Co(en)33+与柠条叶DNA的相互作用.体系式电势E0'的负移和峰电流的下降表明,该配合物与柠条叶DNA有明显相互作用,小分子配合物与柠条DNA可能以非共价方式结合.

关键词: Co(en)33+, DNA, 柠条叶, 伏安法

Abstract: The interaction between Co(en)33+ and DNA of C. Korshinskii treated by polymer plant regulator was probed by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) for the first time in this paper. Adding DNA into Co(en)33+ solution, the i p value of Co(en)33+ decreased and the peak potential shifted negatively, which showed that Co(en)33+ had the ability to bind into DNA. It was of great importance to analyze vegetal growth prowth precess and study the mechamism of polymer plant regulator.

Key words: Co(en)33+, DNA, Caragana korshinskii, Voltammetry
