[Electron microscopical demonstration of polysaccharides in rotifers (Aschelminthes) with the use of OsO4-ferricyanide (author's transl)].
Three species of rotifers were fixed with glutaraldehyde and postfixed in a OsO4-ferricyanide solution. This procedure results in staining of the sarcoplasmic reticulum (SR) and the surface coat of muscle cells as well as in staining of the surface coat of glands and nerve cells. Section-staining with leadcitrate increased the electron opacity of the precipitates, which are interpreted as polysaccharides. The partial decrease of staining of polysaccharides, which sometimes is observed, may be related to processes of function. The precipitates within the SR are considered as glycogen-beta-particles.
