Abstract:
Objective To construct a recombinant plasmid pLEGFP-mIFN? for developing the genetical therapy of tumor by stem cells.Methods PCR was used to amplify the mIFN? gene from plasmid pcDNA3.1-mIFN? in which the mIFN? was cloned.A new plasmid,pLEGFP-mIFN?,was then constructed by inserting the amplified mIFN? gene into pLEGFP-C1.Restriction analysis and sequencing were used to confirm the structure of pLEGFP-mIFN?.Neural stem cells were transfected by supernatant of PA317.Results A DNA fragment in size of 500 bp was amplified.Restriction analysis showed that the amplified gene was inserted into pLEGFP-C1 correctly.(Conclusion The) plasmid pLEGFP-mIFN? is constructed successfully,and it can transfect neural stem cells.
