A Device for Staining Tissue Sections for Electron Microscopy

It has been the experience of this laboratory that the lead hydroxide stain of Watson (1) gives excellent results in increasing contrast in thin sections of tissue, but that the stain is inconvenient to use because on contact with air it forms an insoluble precipitate which contaminates both the stored solution and the sections. 1 Contamination introduced in transferring the solution from the s...

Electron Microscopy of Fowl Pox Virus

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...

A Simple Preparation of Graphite-coated Grids for High Resolution Electron Microscopy

High resolution electron microscopy requires that the specimen supports be smooth. With this in mind a procedure was developed for cleaving single graphite crystals into thin flakes suitable as specimen supports. Fernfindez-Morfin (1) was the first to use graphite and mica crystals for specimen supports. He as well as Sprague (2) obtained the thin sheets of mica and graphite required through su...

Isolation of Herpetosiphon giganteus and Ultrastructure Analysis by Electron Microscopy

Herpetosiphon giganteus is a filamentous gliding bacterium. Gliding motility is the movement of the cells over surfaces without the aid of flagella. The mechanism responsible for bacterial gliding motility has not been known and there are only a few data on Herpetosiphon giganteus. The aim of this study was to observe the ultrastructure and negative staining of isolated strains of Herpetosiphon...
