Abstract
A glycoprotein with an apparent molecular weight of 93 kDa was purifie d from a water-soluble extract of Aspergillus fumigatus NCPF 2109 by s ingle step affinity chromatography using the mannose-specific snowdrop (Galanthus nivalis) lectin coupled to agarose. The carbohydrate moiet y contained only mannose and galactose. Partial sequencing of cyanogen bromide fragments of the antigen yielded two sequences, KQNKP and GEI PMKF?PQL, with no homology to any reported proteins. In a preliminary evaluation of its diagnostic potential the 93 kDa antigen was recogniz ed by the sera of four patients with allergic bronchopulmonary aspergi llosis, in addition to a monoclonal antibody raised against a partiall y purified fraction of the A. fumigatus water-soluble extract.
