ELECTRON MICROSCOPY OF VIRUS-INFECTED YEAST CELLS

Electron Microscopy of Fowl Pox Virus

Scanning electron microscopy of lymphoid cells from leukemia virus-infected mice.

Spleen, lymph node, bone marrow, and thymus cells from Friend leukemia virus (FLV)-infected mice were examined by scanning electron microscopy. Whereas splenocytes from normal, noninfected animals showed the expected morphological classes of lymphocytes, including cells with numerous villous projections and smoother cell types, spleen cells from mice infected with FLV showed a rapid alteration ...

Electron Microscopy of Hela Cells Infected with Adenoviruses

HeLa cells were infected with adenoviruses (types 1-4) and sectioned for electron microscopy after intervals of 20 to 48 hours. Clusters of virus-like particles were found within the nuclei of infected cultures but not in those of uninfected controls. The particles were often arranged in rows as if in crystalline formation. Maximal diameter of particles was approximately 65 mmicro, and internal...

Electron microscopy of cells infected with adenovirus type 2.

An electron microscope study of two strains of human adenovirus type 2 revealed the production of intranuclear paracrystalline formations by one of the strains. The crystals were composed of cylindrical tubules 25.0 nm in diameter arranged in a crystalline lattice with a periodicity of 75.0 nm. They appeared at 36 hr postinfection in nuclei which contained viral particles. Prolonged treatment w...

Immunogold Labeling of Cultured Cells and Virus Particles for Electron Microscopy and Cryo-Electron Microscopy Applications

Cryo-electron microscopy (cryo-EM) and cryo-electron tomography (cryo-ET) were first realized in the early 1980s [1] and mid-1990s [2, 3]. Since then both methods have quickly become a powerful tools in structural biology. The major advantage is that they allow for the acquisition of images of biological specimens persevered in their native state after they are plunge-frozen onto carbon-coated ...
