概要
- 論文の詳細を見る
The local charge of plasmid DNA has been studied using electrostatic force microscopy (EFM). The sample was prepared by immersing plasmid DNA in ZnCl2. The interaction of the tip with the positive local charge was stronger for the DNA immersed in a solution of higher concentration, and this phenomenon was evidence of the positive metallic ion intercalation into DNA.
