Figure 5From: Induction of robust immunity response in mice by dual-expression-system-based recombinant baculovirus expressing the capsid protein of porcine circovirus type 2Antibody responses in mice immunized with of BV-GD-ORF2. Mice were immunized intramuscularly with BV-GD-ORF, pc-ORF2, AcMNPV-WT or PBS. An identical booster immunization was given 3 weeks later. Serum was obtained at 3, 6, and 9 weeks. Antibody levels were analyzed with a Cap-protein-specific ELISA (a) and a serum neutralization assay (b). All data are means ± SD.Back to article page
