Fig. 5From: Establishment of a peptide-based enzyme-linked immunosorbent assay for detecting antibodies against PRRSV M proteinVN titers and ELISA results for sera from pigs immunized with NADC30-like PRRSV inactivated vaccine. A ELISA detected the serum samples collected at 0, 2, 3, 4, 6 and 8 weeks after inoculation. The red horizontal dotted line indicates the cutoff of the IDEXX PRRSV X3 Ab ELISA. The orange yellow horizontal dotted line indicates the cutoff of the M-A110-129 ELISA. The purple horizontal dotted line indicates the cutoff of the M-A148-174 ELISA.
