摘 要:The key to successful gene therapy is tofind a suitable method and carrier for transfection to allow a gene to be transferred into a cell and integrated into the target *** aim of this study was to determine whether biomagnetic material could be combined with the nucleic acid for gene ***-coated iron oxide nanoparticles(DCIONPs)were prepared and mixed with the plasmid pGenesil-1 containing the test gene,which expresses enhanced greenfluorescent protein(eGFP).PGenesil-1 empty vector was used as a *** binding ability was assessed by electrophoresis of the DNA on agarose gels and quantification using BANDS-CAN *** different gene carriers,Lipofecta-mine 2000,Sofast,and DCIONPs,the large intestine cancer(Lovo)cell line was transfected in vitro with or without a magneticfi*** expression of eGFP was observed byfluorescence microscopy,and the transfection efficiency was *** results showed there was a rapid increase in combining rate when the quality ratio of DCIONPs and pGenesil-1 ascended from 1∶1 to 5∶***,the combining rate increased less rapidly as the quality ratio continued *** expression of eGFP showed that the early transfection rate could be improved by applying a magneticfi*** conclusion,the DCIONPs we synthesized are able to carry plasmid DNA and enhance the early transfection efficiency when using a magneticfield.
