Research Abstract |
The aims of this study were to identify wheat proteins in sera of patient with wheat dependent exercise-induced anaphylaxis (WDEIA) during provocation tests using iTRAQ-based analysis, and to evaluate usefulness of CAP-fluorescent enzyme-immunoassay (CAP-FEIA) using recombinant high molecular weight-glutein. In iTRAQ-based analysis, although wheat proteins were detected in patients’ sera, those wheat proteins were not involving with allergic reactions. When recombinant HMW-glutenin was immobilized to CAP-FEIA, it was confirmed that detection of specific IgE anaginst recombinant HMW-glutenin is useful for diagnosis of WDEIA when combined with the CAP-FEIA (recombinant omega-5 gliadin) test.
