title: [The antigenic structure of glycoprotein E2 in the Venezuelan equine encephalomyelitis virus studied using rat monoclonal antibodies].
abstract: A collection of 21 rat hybridomas secreting high-affinity monoclonal antibodies to Venezuelan equine encephalomyelitis (VEE) virus was generated. Using a panel of 15 monoclonal antibodies to glycoprotein E2, the antigenic structure of this protein of VEE strains TC-83 and 230 was studied. A competitive radioimmunoassay suggested a new map of the antigenic structure of glycoprotein E2 in which 5 sites including 11 epitopes of monoclonal antibody binding were distinguished. Antibody to E2-2 site neutralized virus infectivity and blocked hemagglutination test and antibody to E2-3 site could only block hemagglutination. Antibodies to other E2 protein sites lacked any biological activity.
