    Abstract:
    Cockroach allergens have been established as important sensitizing agents in the induction of asthma. In the present investigation, we identified a 36-kD allergen from German cockroach (Blattella germanica) using fast protein liquid chromatography that reacted in the Bla g II monoclonal assay developed by Pollart et al. Defatted whole body German cockroaches were extracted in phosphate-buffered saline and fractionated using gel filtration (Superdex 75) and anion exchange (MonoQ) chromatography. The 36-kD allergen was isolated from this enriched allergen preparation by excision from modified preparative sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) gels, electroelution, dialysis and lyophilization. SDS-PAGE/Western immunoblot analysis using a serum pool of cockroach-sensitive individuals revealed a single band. The lyophilized 36-kD allergen was then analyzed for amino acid composition and digested for peptide amino acid sequencing.
