  • To improve the effect of the gene immunization against Hantaan virus, we constructed the eukaryotic expression vector pTARGET-hans(ISS) containing Hantaan Virus S gene coding region and CpG motif by cloning S gene segment with CpG motif into eukaryotic expression vector pTARGETTM. After conformed by enzyme analysis, the recombinant expression vector pTARGET-hans(ISS) was transferred into Vero-E6 cells by electroporation and the transient expression of Hantaan virus nucleocapsid protein was detected by indirect immunofluorescence assay(IFA). In some transferred Vero-E6, the green fluorescence was showed, thus we can conclude that the eukaryotic expression vector pTARGET-hans(ISS) was successfully constructed and expressed in vitro, which will lay a foundation for further animal vaccination.

    Abstract: To improve the effect of the gene immunization against Hantaan virus, we constructed the eukaryotic expression vector pTARGET-hans(ISS) containing Hantaan Virus S gene coding region and CpG motif by cloning S gene segment with CpG motif into eukaryotic expression vector pTARGETTM. After conformed by enzyme analysis, the recombinant expression vector pTARGET-hans(ISS) was transferred into Vero-E6 cells by electroporation and the transient expression of Hantaan virus nucleocapsid protein was detected by indirect immunofluorescence assay(IFA). In some transferred Vero-E6, the green fluorescence was showed, thus we can conclude that the eukaryotic expression vector pTARGET-hans(ISS) was successfully constructed and expressed in vitro, which will lay a foundation for further animal vaccination.
