Fig. 1 EAST inhibition. A, Patient's serum was preincubated for 1 hour with increasing amounts of either Quorn extract or rFus c 1. After subsequent incubation with mycoprotein immobilized on paper disks, residual IgE-binding capacity was measured. B, Same experiment as before using rFus c 1 immobilized on paper disks.

Fig. 2 Blot inhibition. For each blot strip, serum from the Quorn-sensitized patient was preincubated with either protein of the in-house extracts as indicated or rFus c 1. Detection of the bound IgE antibodies was performed with an alkaline phospatase-conjugated mouse anti-human IgE antibody and NBT/BCIP as substrate.
