To monitor the reactivity of sera to the CP 169e180 epitope, enzyme immunoassays, using BSA-conjugated CP 169e180 peptides and HRPconjugated anti-guinea pig IgG antibodies (Bethyl Laboratories), were performed as described previously. In a competition enzyme immunoassay employing a microtiter plate coated with BSA-conjugated CP 169e180 peptide and HRP-conjugated anti-porcine IgG antibody, the recombinant anti-CP 169e180 antibody almost completely inhibited the binding of naturally occurring anti-CP 169e180 antibody to the peptide in a PCV2-infected pig's sera (Fig. 2) . In an enzyme immunoassay employing a microtiter plate coated with BSA-conjugated CP 169e180 peptide, sera from animals immunized with vaccine A had a significantly higher antibody titer than vaccine B-vaccinated animals (p < 0.01) (Fig. 3D) . ./cache/cord-255936-hfa9w2dg.txt ./txt/cord-255936-hfa9w2dg.txt
