Antibody titer of ALF sera against PDC-E2, BCOADC-E2 and OGDC-E2 obtained at days 1-4, 5-7 days, 12 month and 24 months post ALF. AMA positive ALF sera were serial diluted from 1:40 to 1:2560 and analyzed for their reactivity against recombinant proteins of PDC-E2, BCOADC-E2 and OGDC-E2 by ELISA. Positive sera and negative sera were used throughout as controls. Titer was defined as the highest sera dilution with positive AMA reactivity.
