A simple silver staining technique was applied to serial ultrathin sections of Vicia faba root tip meristems to investigate the structural organization of the nucleoli. The procedure consists of three steps: hydrophilic Lowicryl resin embedding, preparation of ribbons of serial ultrathin sections,
A simple silver staining technique for use at the electron microscopic level, consisting only of treatment with aqueous silver nitrate at high temperature for a prolonged time, was applied to thin sections of root tip meristems of Vicia faba. This technique contrasted the fibrillar component and the
As our previous studies have indicated, the cingulate cortex of the adult mouse brain contains many neurons with rich cell surface glycoproteins which are linked by collagenous ligands to perineuronal proteoglycans. The present study demonstrated that exclusive incubation with
