An assessment of cross reactivity with patients allergic to birch pollen using the immunoblotting
نویسندگان
چکیده
The aim Evaluation of the applicability of immunoblotting for diagnosing cross reactivity between homologous proteins present in various sources. Method and material: Group of 21 patients with birch pollen allergy aged 41,7±5,2 revealing symptoms after eating cross-reacting food and positive skin tests, or prick by prick tests with native food allergens. Control group 7 persons aged 39,8±4,7, allergic to birch pollen without any symptoms after having eaten the above mentioned food. Concentration of asIgE for birch pollen, apple, carrot and celery allergens has been measured with EIA method. Concentration of asIgE against recombinant allergens of birch pollen Bet v1, Bet v2 and celery Api g1 has been evaluated with FEIA-UniCAP 100. As plant material served specially prepared extracts of apples’, separately peel and pulp, as well as of carrot and celery. The detection of proteins following the immunobloting was conducted by incubating in the darkness the nitrocellulose membrane in a buffer solution and peroxidase substrate.

Glutathione-S-Transferase: A Minor Allergen in Birch Pollen due to Limited Release from Hydrated Pollen
BACKGROUND Recently, a protein homologous to glutathione-S-transferases (GST) was detected in prominent amounts in birch pollen by proteomic profiling. As members of the GST family are relevant allergens in mites, cockroach and fungi we investigated the allergenic relevance of GST from birch (bGST). METHODOLOGY bGST was expressed in Escherichia coli, purified and characterized by mass spectro...
متن کاملImmunoblotting in the diagnosis of cross-reactivity in children allergic to birch.
PURPOSE The scientific experiments with new immunological methods (immunoblotting, RAST inhibition) and isolation of recombinant allergens suggest structural similarities in the allergenic components responsible for cross-reactions. Immunochemical and molecular biology studies indicate that epitopes of major allergen (Bet v 1, Mal d 1) contain more IgE binding epitopes than minor allergens (Bet...
متن کاملThe allergen profile of beech and oak pollen.
BACKGROUND Beech and oak pollen are potential allergen sources with a world-wide distribution. OBJECTIVE We aimed to characterize the allergen profile of beech and oak pollen and to study cross-reactivities with birch and grass pollen allergens. METHODS Sera from tree pollen-allergic patients with evidence for beech and oak pollen sensitization from Basel, Switzerland, (n=23) and sera from ...

Material and Methods The clinical history and the positive SPT with the birch extract were the condition for qualifications. 23 patients included in the first group were only birch allergic. 35 patients in the other group had birch pollen allergy and they reported symptoms after eating apple, celery, carrot, tomato, banana, peach, peanut and hazelnut. The skin tests were performed and serum IgE...
متن کاملCross-Reactivity between Oak and Birch Pollens in Korean Tree Pollinosis
Oak and birch trees belong to Fagales order. Specific IgE to pollen allergens of both trees are frequently found in Korea pollinosis patients. Oak trees which comprise 40% of forest area are common in Korea. However, birch trees are sparse. We compared the allergenicity of pollen extracts of white oak, sawtooth and Mongolian oaks which are prevalent species in Korea, with the pollen extract of ...
