title: Isolation of the Maclura pomifera hemagglutinin on a deoxymelibiotol affinity support and preliminary characterization by buffer electrofocusing and high-performance liquid chromatography.
abstract: Maclurin, the potent non-specific blood-group hemagglutinin present in extracts of Maclura pomifera, has been purified by a new biospecific affinity-chromatographic procedure. Additional studies have indicated that this hemagglutinin occurs as five closely related tetrameric protein isoforms derived from two non-covalently-linked polypeptide chains, mol. wts. ca. 10,000 and 13,000 respectively. Buffer electrofocusing fractionated the lectin into 12 components; the major isolectin exhibited an isoelectric point at pH 4.8.
