Abstract:
Objective To construct a recombinant plasmid for expressing the HPV18 E2 gene and develop some materials for HPV18 related disease.Methods The E2 gene of HPV18 was amplified by PCR from PBR322-HPV18 and cloned into PIRES2-EGFP.The sequence of cloned HPV18E2 was confirmed by restriction analysis and DNA sequencing,then transfected into HeLa cells.E2 gene was detected by RT-PCR.Results HPV18 E2 gene fragment was amplified by PCR and ligated to PIRES2-EGFP,then transfected into HeLa cells successfully.The expression of green fluorescence cells was observed by fluorescence microscopy.Specific band could be seen in transfected cells by RT-PCR.Conclusion Recombinant plasmid PIRES2-EGFP is effectively expressed after being transfected into HeLa cells in vitro.
