Abstract:
A monoclonal antibody (mAb), named 1.21, with complement-dependent neutralizing activity was produced against glycoprotein II (gII) of pseudorabies virus (PRV). By immunoaffinity chromatography using a mAB 1.21 column, gII was purified from Nonidet P40-lysates of PRV infected BHK21/13 cells. When mice and pigs were immunized with purified gII, complement-dependent virus-neutralizing antibodies were produced. The immunized animals survived potentially lethal challenge with PRV. These results indicate that an immunological response against gII plays an important role in the protection from PRV infection.
