Abstract:
Two plasmid constructs, pcE2 and pcE3, containing 3' fragment of open reading frame 2 (ORF2,1163 bp) of hepatitis E virus (HEV) and full-length ORF3 (369 bp), were injected into bilateral tibialis of Swiss mice respectively，for three times (0, 2nd and 4th weeks) and observed the HEV IgG by ELISA. HEV IgG was induced after the injection of pcE2 or pcE3 or both, and the percentage of seraconversion was 100% after two weeks of the third injection. Compared with injection of either construct, the antibody titers were higher in the group with combined injection of two constructs.
