摘要: N-Methylene phosphonic chitosan (NMPCS), an amphiphilic macromolecule with powerful chelating ability of Ca²⁺ ions, was synthesized and characterized. The physicochemical properties of NMPCS and the interactions between NMPCS and plasmid DNA were investigated by FTIR, ¹³C NMR, X-ray, agarose gel electrophoresis retardation assay, atomic force microscopy (AFM) and complexes with mean size of 80-210 nm were formed. Taking HeLa as host cell, luciferase expression mediated by NMPCS improved about 100 times compared to the expression mediated by chitosan.
