title: Lectin-like components in the macronuclear replication bands of Euplotes eurystomus.
abstract: Upon incubation with fluoresceinylated neoglycoproteins, isolated macronuclei from the ciliated protozoan Euplotes eurystomus display different labelling patterns depending on the nature of the sugar bound to the neoglycoproteins. Specific sugar-binding components (i.e., lectin-like molecules) are associated with presumed nucleoli and with the macronuclear replication bands. This is the first demonstration that DNA synthesis and sugar-binding components are co-localized in an eukaryotic cell.
