Background and Objective: Numerous studies on Clasporidium herbarum antigens have shown that these antigens play a major role in produceing specific IgE in atopic individuals and exacerbate the patients’ clinical conditions like atopic dermatitis. Thus, in this study allergenic components of clasporium herbarum were investigated using immunoblotting technique. Materials and Methods: Cladosporiu...
aspergillus species (a flavus and a niger) are important sources of inhalant allergens. current diagnostic modalities employ crude aspergillus extracts which only indicate the source to which the patient has been sensitized, without identifying the number and type of allergens in crude extracts. we report a study on the identification of major and minor allergens of the two common air...
Background: Food hypersensitivity to walnut usually results in mild symptoms; however, several cases of anaphylactic reactions to this product have been observed. This study aimed to determine the immunochemical characteristics of the Persian walnut and provide the recombinant form of its main allergen. Materials and Methods: The allergenic proteins of th...
The present study describes the occurrence of an anaphylactic reaction after the administration of the fifth booster dose of DT vaccine in a six-year-old child. Skin test, in vitro determinations of specific IgE antibodies and immunoblotting assays showed that the IgE response was directed against tetanus and diphtheria toxoids (Dtx). IgG antibodies were also detected by ELISA and immunoblottin...
BACKGROUND Our group previously found that up to 7% of amateur anglers in Caceres, Spain may be allergic to the larvae of Protophormia terraenovae (order Diptera, family Calliphoridae) used as live bait for fishing. OBJECTIVE To identify the pattern of major allergens in P terraenovae and other species of Calliphoridae. MATERIALS AND METHODS Extracts of P terraenovae, Calliphora vomitoria, ...
In Korea, common whelk (Buccinum undatum) is a popular edible shellfish. The aim of this study was to observe the sensitization rate to common whelk and to characterize its allergens. We carried out skin prick test (SPT) in 1,700 patients with various allergic diseases. Specific IgE were detected by ELISA in the patient sera and ELISA inhibition tests were conducted. IgE-binding components were...
siifolia) pollen were investigated by mass spectrometry (MS), 2D-PAGE and immunoblotting. Furthermore, Amb a 1 isoallergens were purified and IgE reactivity determined by immunoblotting and IgE inhibition. Results: 2D-PAGE and MS of ragweed extract proved the presence of all 5 known Amb a 1 isoallergens, of which Amb a 1.01 represents the dominant form. Additionally all other ragweed allergens ...

Abstract Background and objective: Being exposed to different allergens, followed by the production of specific IgE, has an important role in causing atopic dermatitis, recognizing the allergens and applying immunotherapy for treatment. We aimed to determine the frequency of common allergens in the patients suffering from atopic dermatitis. Material and Methods: In this descriptive- anal...
