PCV2-specific immune responses induced by Cap-E2 NPs. Mouse sera collected at 14 and 28 dpi (days post-immunization) were further analyzed. A indirect ELISA was used to assess binding of serum IgG to native Cap VLPs. B The avidity of Cap-specific IgG from mouse sera at 28 dpi was measured by avidity ELISA. C Mouse sera at 28 dpi were tested by VNT to quantify PCV2 JH specific neutralizing antibodies. ns, p > 0.05
