A. fumigatus allergen I/a (rAsp f I/a) was produced in Escherichia coli, affinity purified by Ni(2+)-chelate chromatography and refolded. rAsp f I/a binds IgE of A. fumigatus-allergic individuals as shown by ELISA, dot blots and Western blots. In addition, rAsp I/a elicited positive immediate type I skin reactions in individuals allergic to A. fumigatus but not in control individuals. Hence, rAsp f I/a can be used as a standardized antigen/allergen for an improved serological and clinical diagnosis of A. fumigatus-associated diseases.
