title: Antigenic properties of the Golgi derived scales of Pleurochrysis scherffelii.
abstract: The cell wall of the marine alga Pleurochrysis scherffelii is composed of Golgi-derived scales with four distinct subcomponents: amorphous coating material, radial microfibrils, spiral coating substances and spiral microfibrils. The antigenic properties of the Pleurochrysis scales were studied. Antibodies were produced in rabbits to the amorphour to the amorphous coating material and to a heretofore undescribed peripheral subcompoent, known as the amorphoous rim modification substance. The antigenic subcomponents were detected by agglutination/precipitation, negative staining, and shadowing procedures. Scales of the Cricosphaera phase produced negative results when tested with Pleurochrysis scale antisera. A possible function of the amorphous rim modification substance in maintaining the integrity of spiral microfibrillar organization is introduced.
