From: Lineage specific antigenic differences in porcine torovirus hemagglutinin-esterase (PToV-HE) protein
Reactivity of sera obtained from pigs at different ages against PToV-HE52.7 and PToV-HE52.11 determined by ELISA. Purified HE52.7-myc- and HE52.11-myc proteins were used as coating antigen (62.5 ng/well). The same serum samples analyzed in Figure 4 were used in the ELISA at a 1:100 dilution. IgG ELISA reactivities against HE52.7-myc- (panels A, C and E) and HE52.11-myc (panels B, D and F) of serum samples from pigs and their sows are represented.
