Polyacrylamide gel electrophoresis (PAGE) of serotype II IBDV (OH and MO strains) purified from infected Vero cells resolved a previously undetected major viral polypeptide, VP2. The molecular weight (MW) of VP2 was different between the two strains of serotype II. It was 43.5 kDa in strain OH and 44 kDa in strain MO. This was higher than the MW of VP2 in SAL strain of serotype I IBDV which was 41 kDa. VPX (50 kDa), VP3 (33 kDa) and VP4 (30.5 kDa) were similar in both serotype II virus strains but were also of higher MW than VPX (48 kDa), VP3 (32 kDa) and VP4 (30 kDa) of SAL virus. VP1 (80 kDa) had the same MW in both serotypes.
