Cytochemical Staining of the Golgi Apparatus in Amoeba Proteus
The Golgi apparatus has been shown to be involved in the packaging of secretory proteins (Caro and Palade, 1964 ; Jamieson and Palace 1967 a, 1967 b), and in the production of acid mucopolysaccharides and glycoproteins (Neutra and Leblond, 1966 ; Berlin, 1967 ; Thiéry, 1967 ; Rambourg et al, 1969; Whur et al., 1969) . Other suggested functions of the Golgi apparatus include the formation of the...
متن کاملMorphological and Cytochemical Identification of the Golgi Apparatus
1. A modification of Elftman's direct silver method reveals both the lipochondria of Baker and the network of Golgi in the same cell. For purpose of distinction, it is proposed to call Baker's lipochondria the nucleopetal fraction, the Golgi network the nucleofugal fraction of the Golgi apparatus. 2. The nucleopetal fraction is located closer to the nucleus. It is spherical in shape and appears...
متن کاملCytochemical Staining of Multivesicular Body and Golgi Vesicles
To investigate the origin and nature of vesicles found within multivesicular bodies (mvb), the cytochemical staining properties of mvb vesicles were compared with those of other cytoplasmic vesicles, i.e. those associated with the Golgi complex and endocytic vesicles found near the apical cell surface. Rat epididymal tissue was stained in unbuffered OsO(4) for 40-48 hr, and the distribution of ...
متن کاملFilaments of Amoeba Proteus
Amoeba proteus has two types of cytoplasmic filaments that are thought to be important in cell motility, cytoplasmic streaming, and changes in cytoplasmic consistency : thin, 50-70 A wide filaments, and short, thick, 160 A wide rods (Pollard and Ito, 1970) . The thin filaments resemble the actin filaments of muscle (Hanson and Lowy, 1963), Acanthamoeba (Weihing and Korn, 1969 ; Pollard et al .,...
متن کاملStructure of Isolated Plant Golgi Apparatus Revealed by Negative Staining
Sucrose-gradient-purified dictyosomes of plant Golgi apparatus appear, after glutaraldehyde stabilization, as stacks of highly fenestrate and tubate cisternae when negatively stained with phosphotungstic acid, shadowed with heavy metal, or OsO(4)-stained in thin section. The tubular proliferations (diameter 200 to 400 A) extend for several microns from the central region and are united at inter...
