[Retracted] Construction and Immunogenicity of DNA Vaccines Encoding Fusion Protein of Porcine IFN-1 and GP5 Gene of Porcine Reproductive and Respiratory Syndrome Virus
Figure 6
Lymphocyte proliferative responses of mice immunized with different DNA constructs. Mice were immunized as in Figure 4. Mice splenocytes samples () were collected at 6 weeks after primary immunization and restimulated in vitro with purified PRRSV proteins (20 μg/mL). Lymphocyte proliferative assay was performed as described in Section 2. Data are presented as the mean ± S.D.
