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 2 and Ara h 6 have similar allergenic activity and are substantially redundant.
BACKGROUND The moderately homologous (approx. 60%) proteins Ara h 2 and Ara h 6 are the most potent peanut allergens. This study was designed to define the relative individual contributions of Ara h 2 and Ara h 6 to the overall allergenic activity of a crude peanut extract (CPE). METHODS Ara h 2 and Ara h 6 were removed from CPE by gel filtration chromatography. Ara h 2.01, Ara h 2.02 and Ara...
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 کاملCompetitive inhibition ELISA for quantification of Ara h 1 and Ara h 2, the major allergens of peanuts.
Allergies to peanuts are becoming an increasingly important health problem as a result of the persistence and severity of the reaction in allergic individuals. Because no treatment currently is available, avoidance is the only option for peanut-allergic individuals. Avoidance of an abundant and often disguised food such as peanuts, however, is very difficult; therefore, competitive inhibition E...
