    Abstract:
    Two monoclonal antibodies against birch pollen proteins were produced by immunizing BALB/c mice with birch pollen extract. In immunoblotting experiments, antibody BIP 1 reacted with a 17-kilodalton (kD) protein considered to represent the major birch pollen allergen Bet v I. A second monoclonal antibody, BIP 3, reacted with 3 different birch pollen proteins of molecular weights 32, 36 and 68 kD of which the 36- and 68-kD proteins corresponded to minor allergens of birch pollen. Two-dimensional electrophoresis/immunoblotting experiments revealed that BIP 1 reacted with all Bet v I isoallergens, also identified by human IgE antibodies. Using BIP 1 coupled to Sepharose 4B as reverse immunosorbent, Bet v I was obtained in a single-step procedure and characterized as single band by SDS-PAGE.
