Mannose- and fucose-rich glycoproteins are highly abundant and predominantly localized on scales and suckers of adult flukes. Flat fixed whole adult flukes were probed with fluorescein-labeled mannose, fucose and complex oligosaccharide-binding lectins (green) and, where displayed, with DAPI nuclear staining (blue). Lectin blots represent tegumental proteins (15 μg), probed with mannose, fucose and complex oligosaccharide biotin-labeled lectins orIR-labeled streptavidin complex (green), molecular mass marker (red).
