Figure 6From: Induction of robust immunity response in mice by dual-expression-system-based recombinant baculovirus expressing the capsid protein of porcine circovirus type 2The IFN-γ response in splenocytes harvested from immunized mice was measured by ELISA. Mice were immunized as in Figure 5. Splenocytes were isolated at 6 weeks after the primary immunization and stimulated with or without purified Cap protein in vitro for a defined time. The IFN-γ levels in the supernatant were analyzed with an ELISA. Data are means ± SD.Back to article page
