IgE cross-reactivity between the major peanut allergen Ara h 2 and the non-homologous allergens Ara h 1 and Ara h 3
BACKGROUND Ara h 1, a vicilin; Ara h 2, a 2S albumin; and Ara h 3, a legumin, are major peanut allergens. Ara h 2 is an important predictor of clinical reactivity to peanut, but cosensitization to all 3 allergens is correlated with the severity of patients' symptoms. OBJECTIVE We investigated whether cosensitization to these 3 allergens is caused by IgE cross-reactivity, despite the fact that...
متن کاملAra h 6 complements Ara h 2 as an important marker for IgE reactivity to peanut
The similarities of two major peanut allergens, Ara h 2 and Ara h 6, in molecular size, amino acid sequence, and structure have made it difficult to obtain natural Ara h 6 free of Ara h 2. The objectives of this study were to purify natural Ara h 6 that is essentially free of Ara h 2 and to compare its IgE reactivity and potency in histamine release assays to Ara h 2. Sodium dodecyl sulfate-pol...
متن کاملImpedance biosensor for peanut protein Ara h 1.
A reagentless electrochemical impedance biosensor for detection of peanut protein Ara h 1, one of the allergenic proteins found in peanuts, has been demonstrated using an Au substrate onto which an antibody film has been immobilized. Following initial stabilization of the self-assembled monolayer (SAM) through which the antibody is immobilized, the biosensor substrate exhibits stable impedance ...
متن کاملImportance of Ara h 6 in peanut allergy diagnosis
Results Twenty-two children (median age: 6.63 y.o.; IQR: 5.22-10.12) were classified as allergic in the basis of at least two convincing clinical reactions upon ingestion of PNT in the last two years. Sixty-nine children (median age: 8.01 y.o.; IQR: 6.01-11.27) were classified as tolerant on the basis of regular consumption of PNT. Positive SPT with commercial PNT extract was found in 86% of th...
متن کاملPeanut allergen (Ara h 1) detection in foods containing chocolate.
Inadvertent exposure to peanut in foods poses health risks for peanut-allergic individuals that can be reduced by improving detection systems for allergen contaminants in food products and manufacturing processes. Detection of peanut in chocolate has been especially difficult. We report the optimization of conditions for measuring a major peanut allergen, Ara h 1, in chocolate with the use of a...
