Abstract: The fusion VP3 gene sequence of goose parvovirus (GPV) was amplified by PCR using a pair of specific primers from GPV FY89 strain.The PCR product was cloned into pFastBac/HBM-TOPO vector and transformed into DH10Bac cells.Recombinant Bacmid-VP3 was transfected into Sf9 insect cells,and a fusion protein about 61 ku was expressed and identified by SDS-PAGE analysis.The antigenicity of the recombinant VP3 protein was confirmed by Western blotting.

Key words: goose parvovirus (GPV); VP3 gene; baculovirus expression system
