[Retracted] Construction and Immunogenicity of DNA Vaccines Encoding Fusion Protein of Porcine IFN-𝝀1 and GP5 Gene of Porcine Reproductive and Respiratory Syndrome Virus

Figure 4

The titers of GP5-specific ELISA antibody in mice immunized with different DNA constructs. Six-week-old BALB/c mice (seven per group) were immunized intramuscularly with 100 μg of pcDNA3.1-PoIFN-λ1-SynORF5, pcDNA3.1-SynORF5, and pcDNA3.1 (+), respectively, at 0 and 2 weeks. Serum samples were collected at 2, 4, and 6 weeks after primary immunization to determine the GP5-specific ELISA antibody. Data represent the mean and S.D. for 7 mice per group.
