title: Cytochrome c allergens isolated from the pollens of the dicotyledons English plantain (Plantago lanceolata) and Paterson's curse (Echium plantagineum).
abstract: Two cytochrome c allergens were isolated from extracts of the pollens of the dicotyledons English plantain (Plantago lanceolata) and Paterson's Curse (Echium plantagineum) by ion exchange chromatography, gel filtration and preparative isoelectric focusing. They were characterized by their absorption spectra, mol. wt, pI and amino acid composition. The cytochromes c bound specific IgE in the sera of hypersensitive patients by RAST. Preliminary evidence for allergenic cross-reactivity between them was obtained by RAST inhibition.
