The interactions of dsDNA and ssDNA with two osmium complexes have been studied by surface electrochemical methods based on DNA modified electrode. It is found that both osmium complexes bond DNA with electrostatic interaction. And some thermodynamics and kinetics constants, such as bindind constant , ratio of binding constants K〓/K〓, limiting ratio K〓°/K〓°at zero ionic strength (μ＝0), free energy ΔG〓, dissociation rate constant k and binding site size s have been obtained.
研究发现两种锇配合物都是通过静电作用与DNA结合，并计算得到联吡啶锇和二氯菲咯啉锇与dsDNA和ssDNA相互作用的结合常数、结合常数比K〓／K〓、μ＝0时极限结合常数比K〓°／K〓°、结合自由能ΔG〓、解离速度常数k和结合位点数s等多个热力学和动力学参数。

Briefly, coronal brain sections (100 mm)were cut with a vibratome, postfixed with 4% glutaraldehydein 0.1 mmol/L cacodylate buffer (pH 7.4) for 1 h, andthen with 1% osmium tetroxide in 0.1 mmol/L cacodylatebuffer for 2 h. After rinsing with distilled water, the brainsections were treated with 1% aqueous uranyl acetateovernight, dehydrated in an ascending series of ethanolsto 100%, followed by dry acetone, and then embedded inDurcupan ACM. Ultrathin sections (0.1 mm) were cut andstained with 3% lead citrate and subsequently examinedwith a Zeiss transmission electron microscope (Zeiss Inc.,Thornwood, NY, USA).
