RESUMO
The class E immunoglobulins (IgE) is known to recognize conformational epitopes and therefore the native conformation of recombinant allergens is essential for their using in test-systems. Recombinant Dermatophagoides farinae house dust mite (HDM) allergens Der f1 and Der f2 were expressed in bacteria Escherichia coli and Nicotiana benthamiana plants. It has been shown that IgE in sera from children allergic to HDM recognizes Der f2 expressed both in E. coli and N. benthamiana. Mature form of Der f1 expressed in E. coli does not interact with IgE while the protein purified from N. benthamiana is able to recognize IgE as a native allergen.
