BACKGROUND Exposure to the house dust mite Blomia tropicalis is increasingly being implicated as a major risk factor for asthma exacerbations in sensitized individuals. The objective of this study is to clone and characterize B. Tropicalis allergens in order to better define their role in allergic

Previous studies have shown that the domestic mites Dennatophagoides pteronyssinus and D. farinae contain allergens with serine protease activity. These proteolytic allergens include trypsin, chymotrypsin, elastase, kallikrein, and C3/C5 convertase. However, it is not known whether the domestic mite

BACKGROUND House dust mite allergens have been shown to be a very important stimulus in the causation of asthma and triggers for the exacerbation of symptoms. Therefore, characterization of mite-derived allergens at the molecular level is an important step for the development of effective diagnostic

OBJECTIVE To produce and characterize monoclonal antibodies (mAbs) against whole body extract of the dust mite Blomia tropicalis (Bt). BACKGROUND Bt is an important source of allergens causing allergic diseases in tropical and subtropical regions. mAbs are excellent tools for delineating

The majority of important allergenic extracts from arthropods present enzymatic activity. This activity has been studied particularly in Dermatophagoides house dust mites because of its implication in the stability and immunogenicity of extracts used as tools for the diagnosis and specific treatment

BACKGROUND Blomia tropicalis is an important mite species in the tropics and subtropical regions of the world. It is well established that the allergen from this species of mite is one of the triggering factors for allergic asthma. The isolation and characterization of allergens in this mite species
