title: Identification of bovine herpesvirus-1 polypeptides involved in serum neutralization.
abstract: Bovine herpesvirus (infectious bovine rhinotracheitis virus)-infected cell antigens were solubilized with Nonidet P-40. The crude antigen extract was separated by reaction with bovine hyperimmune serum in line immunoelectrophoresis; individual immunoprecipitates were used to immunize rabbits. Rabbit sera possessing serum neutralizing activity were analyzed by reaction with crude antigen extract in immunoprecipitation sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot. Four virus-specified glycopeptides, with molecular weights of 69-75K, 77-81K, 82-92K and 108-115K, appeared to be involved in inducing serum neutralizing antibody.
