Abstract
AIM
To construct a recombinant cherimal plasmid of HCV-Fc that can express HCV core protein and IgG Fc.
METHODS
The HCV core gene derived from the plasmid pBRTM/HCV1-3011 by using polymerase chain reaction (PCR) was inserted into the backward position of cytomegalovirus (CMV) immediate early promotor element of Fc plasmid (pIgFc), then the recombinant plasmid pHCV-IgFc was obtained.
RESULTS
The insert DNA of pHCV-IgFc was HCV core and Fc gene conformed by endonuclease, PCR and sequencing. HCV core gene and Fc gene expressed transiently with Lipofectamine 2000 coated in human hepatoblastoma 7721 cells, which was conformed by immunofluorescence.
CONCLUSION
Recombinant cherimal plasmid vector pHCV-IgFc can express HCV core and Fc gene transiently in 7721 cells. It may be useful in transfection of dendritic cells and development into dendritic cell vaccince.
