title: Efficient induction of Semliki Forest virus and mumps virus neutralizing anti-anti-idiotypic antibodies using Quil A as adjuvant.
abstract: Rabbit anti-idiotypic sera were prepared against Semliki Forest virus (SFV) neutralizing monoclonal antibody (MAb) UM 1.13 and mumps virus neutralizing MAb UM 10B. From these sera anti-idiotypic antibodies were purified by ammonium sulphate precipitation and subsequent affinity column chromatography. Anti-iso- and anti-allotypic antibodies were removed by binding to normal mouse serum immunoglobulins coupled to CNBr activated Sepharose. Peak protein fractions eluted from columns loaded with homologous MAb were used for anti-anti-idiotypic immunization of BALB/c mice to raise virus neutralizing anti-anti-idiotypic antibodies. Two intracutaneous immunizations, five weeks apart, with affinity purified rabbit polyclonal anti-idiotypic antibody (40 micrograms protein per animal) coupled to keyhole limpet hemocyanin and mixed with the adjuvant Quil A (50 microliters per animal) were sufficient to evoke neutralizing antibodies against either virus. Moreover the mice who developed SFV neutralizing serum antibodies upon anti-idiotypic immunization all survived an otherwise lethal challenge with virulent SFV.
