  1. Characterization of soybean allergens causing sensitization of occupationally exposed bakers.

    Article - En anglais

    Fourteen bakers suffering from workplace-related respiratory symptoms and sensitized to soybean were studied.

    Twelve of them were also allergic to wheat flour, 10 to rye flour, and five to alpha-amylase of Aspergillus oryzae (Asp o 2).

    IgE estimation by RAST strongly indicated that the trypsin inhibitor and lipoxidase are major allergens of soybean.

    Various allergenic components could be characterized by immunoblotting after two-dimensional electrophoresis.

    Our RAST and immunoblotting results show an interindividually different allergic response to inhalative soybean constituents, and that the trypsin inhibitor (20 kDa, pI~4.5) is an important inhalative soybean allergen recognized by IgE antibodies in the sera of 86% of the examined sensitized bakers.
