Abstract
A host type non-virus gene delivery carrier, phenanthroline-β-cyclodextrin derivative host molecule, was produced which can be used as molecular probe. Interactions between DZY-1 and DNA were investigated by electrophoresis assay. Hind III enzyme inhibition assay was carried out using DNA condensates induced by host molecules or host-guest molecule complexes to explore their ability to inhibit enzyme digestion. Micro-structure of DNA condensates induced by host molecules and host-guest molecule complexes was observed by scanning electron microscope (SEM). Our work indicates the delivery mechanism of DZY-1 used as a gene delivery carrier and also provides a method to design and produce non-virus gene delivery carriers.
