Viral protein 2 (VP2) of porcine parvovirus (PPV) is the major viral structural protein and is responsible for eliciting neutralizing antibodies in immunized animals. In this study, we constructed and characterized a recombinant yeast vector encoding the VP2 protein, designated as pGAPZαA-VP2. The construct was confirmed by restriction enzyme digestion, PCR, and sequencing and then introduced into P. pastoris strain SMD1168 by electroporation. The expressed VP2 protein was analyzed by SDS-PAGE and western blot. Immunization of mice with the VP2 protein elicited a PPV-specific humoral immune response. Notably, a preparation of VP2 protein containing adjuvant induced a much better antibody response than VP2 alone. Clearly, the adjuvant strongly enhanced the immunogenicity of VP2. This study provides a foundation for the application of the VP2 protein in the clinical diagnosis of PPV and in vaccination against PPV in the future.
