Selective Deposition of Lanthanum in Mammalian Cardiac Cell Membranes
Perfusion of beating false tendons of the dog heart with ionic lanthanum produced drastic but reversible modifications of the excitability and the transmembrane action potential of Purkinje cells. Ultrastructural examination of these cells revealed the appearance of a fine extracellular precipitate detectable on unstained sections. In addition, specimens perfused with La(+++) showed a striking ...
متن کاملLanthanum Staining of the Surface Coat of Cells
Among the techniques which have been reported to stain the surface coat of cells, for electron microscopy, is lanthanum staining en bloc. Similarly, the presence of the cationic dye, Alcian blue 8GX, in a primary glutaraldehyde fixative has been reported to improve the preservation of the surface coat of cells of many types; however, the preserved coat is not very electron opaque unless thin se...
متن کاملLanthanum Staining of Developing Chick Cartilage and Reaggregating Cartilage Cells
In this report intercellular material in developing cartilage and between reaggregating cartilage cells has been examined with lanthanum staining (3, 7, 13, 16) . The proteinpolysaccharides of cartilage have been extensively studied by biochemical methods (2, 8-10, 18-21), and proteinpolysaccharide extracted from cartilage has been shown to precipitate with lanthanum (2) . The lanthanum-stainin...
متن کاملLocalized Lanthanum Staining of the Intestinal Brush Border
The use of lanthanum salts has made possible the staining of extracellular regions which are not electron opaque when conventional methods of fixation and staining for electron microscopy are employed (3, 6, 10). The present work describes the staining of the intestinal epithelium by this means. Intercellular regions in the intestinal wall generally stain intensely, as has been described previo...
متن کاملLanthanum staining of neurotubules in axons from cockroach ganglia.
The axoplasm of the neurons of Penplaneta amencana contains numerous neurotubules which are morphologically similar to the microtubules found in non-nervous tissues after sectioning or negative staining. In cross-sections of fixed material such tubules usually appear as electron-dense circles containing a less dense core and surrounded by a non-opaque ' clear zone'. However, when cockroach gang...
