Antibody response to E2 glycoprotein induced in mice by immunization with plasmid DNA containing sequence derived from a Chinese genotype III/2a isolate of hepatitis C virus.
OBJECTIVE
To induce antibody response against E2 glycoprotein derived from a Chinese genotype III/2a isolate of hepatitis C virus (HCV) in BALB/C mice by plasmid DNA-based immunization.


METHODS
Plasmid p3W14 containing E2/NS1 gene derived from a Chinese genotype III/2a isolate of HCV, which was verified to express 70 kDa E2 glycoprotein in NIH3T3 cells, was used for direct intramuscular injection in BALB/C mice. Specific antibody to E2 glycoprotein was detected by recombinant E2 protein.


RESULTS
Specific anti-E2 antibody could be detected in mice inoculated with p3W14(5/6). Titer of antibody ranged from 1:15 to 1:120.


CONCLUSIONS
Successfully inducing anti-E2 antibody in mice by plasmid DNA-based immunization containing E2/NS1 gene from a Chinese genotype III/2a isolate of HCV is the first time in China.
