CSFV-specific humoral immune responses induced by Cap-E2 NPs. Serum samples were collected for detection of CSFV E2 specific antibodies at 14 dpi (A) and 14 dpi (B) with indirect ELISA. C The avidity of the E2-specific IgG from mice sera at 28 dpi was measured by avidity ELISA. D A standard VNT was performed to evaluate neutralizing antibodies against CSFV Shimen strain. ns, p > 0.05; *p < 0.05; **p < 0.01
