Competitive inhibition of IgE binding to solid phase–coated A. fumigatus recombinant P2 protein. Serum from A. fumigatus–sensitized patients was preincubated with increasing amounts of recombinant A. fumigatus (○), human P2 protein (•), or Asp f 1 as negative control (□). Preincubated serum samples were transferred to wells coated with A. fumigatus P2 protein, and bound IgE was analyzed by antigen-specific ELISA (8, 16).
