our aim in this study was to identify and characterize allergic proteins in cooked wolf herring fish. we heated the crude extract alternatively at 50, 60, 70, 80, 90, and 100°c for one hour and results were compared by sodium dodecyl sulfate polyacrylamide gel electrophoresis (sds-page). also, proteins were immunoblotted with fish-sensitive patients’ sera. the major allergenic proteins were ide...
Chenopodium album is a weedy annual plant in the genus Chenopodium. C. album pollen represents a predominant allergen source in Iran. The main C. album pollen allergens have been described as Che a 1, Che a 2, and Che a 3. The aim of this work was to clone the Che a 1 in Escherichia coli to establish a system for overproduction of the recombinant Che a 1 (rChe a 1). In order to clone this aller...
BACKGROUND Birch pollen is the major allergen in pollinosis in northern Japan. IgE reactivity to individual birch pollen allergens has been shown to differ between populations of birch pollen-allergic patients living in different countries. In this study, we examined the IgE profiles to recombinant birch pollen allergens in birch-sensitive patients living in Sapporo. METHODS This study used t...
BACKGROUND The allergens responsible for cashew food allergy have not been well characterized. OBJECTIVES We initiated a study to clone cDNAs encoding cashew food allergens. METHODS A cashew cDNA library was screened with human serum for IgE-reactive clones and rabbit IgG anti-cashew extract antisera. Reactive clones were sequenced and expressed, and linear epitopes were identified by means...
Allergic diseases, such as allergic asthma, allergic rhinitis and atopic eczema, are a major health problem world-wide, affecting up to 30% of the population. A large proportion of the patients are allergic to indoor allergens, such as mite and cat allergens, which are airborne and thus cause symptoms in the airways upon inhalation. Hundreds of single allergens from different sources have been ...
The grass pollen allergen, Phl p 7, belongs to a family of highly cross-reactive calcium-binding pollen allergens. Because Phl p 7 contains most of the disease-eliciting epitopes of pollen-derived calcium-binding allergens, hypoallergenic variants were engineered according to the x-ray crystal structure of Phl p 7 for allergy vaccination. In three recombinant variants, amino acids essential for...
