METHODS The HCV core gene coding region was inserted into the eukaryotic expressive plasmid pcDNA3, then the recombinant plasmid pcDNAHCV-C was constructed and expressed transiently with LipofectAMINE in the SP2/0 cells. After purification, these plasmid directly or encapsuled wit h Lipofect-AMINE were injected into BALB/c mice. HCV core antibody from immunized mice could be detected by ELISA. RESULTS The enzyme -cutting identification showed that HCV core gene fragment had been cloned into pcDNA3 eukaryote vectors.
