| Abstract: | Hybridoma cell lines producing monoclonal antibodies to pseudorabies virus (PRV) were established. The monoclonal antibodies were characterized with respect to their antigenic specifications and biological activities. Two monoclonal antibodies immunoprecipitated the 50 kDa PRV glycoprotein (gp50) and two immunoprecipitated the 82 kDa glycoprotein (gp82). The monoclonal antibodies were used to analyze the biological roles of these two glycoproteins. One monoclonal antibody directed against each glycoprotein did not require complement for in vitro viral neutralization while the other monoclonal antibody directed against the glycoprotein required complement for neutralization. The monoclonal antibodies against gp50 were shown to be directed against different epitopes within the glycoprotein. In contrast, the monoclonal antibodies against gp82 were shown to be directed against the same antigenic site on the glycoprotein. In vivo passive immunity studies in mice showed that monoclonal antibodies directed against either gp50 or gp82 could be protective. |
