title: Characterization of anti-idiotype reagents to bovine herpesvirus-1 monoclonal antibody.
abstract: A monoclonal antibody (MAb) to a neutralization epitope on the 97-kD glycoprotein of bovine herpesvirus-1 (BHV-1) was used to prepare an anti-idiotypic antibody in rabbits. Purified F(ab')2 fragments of the MAb were used to immunize the animals and the sera containing the greatest anti-idiotype activity were identified by ELISA. After digestion of the immunoglobulins with pepsin and purification by affinity chromatography, anti-idiotype F(ab')2 fragments reacted specifically with the MAb in ELISA. Binding of the anti-idiotypic (anti-id) antibody was inhibited by preincubation of the MAb with BHV-1. Using an ELISA inhibition assay with BHV-1, the anti-id reagent inhibited the binding of anti-BHV-1 MAb to BHV-1, suggesting that the anti-id mimics an epitope of the 97-kD glycoprotein by binding the antigen combining site of the MAb. Development and characterization of this anti-id and future studies of its immunomodulatory effects are discussed.
