Fixation of Bacterial L Forms for electron Microscopy

Detection of rotavirus by Latex Agglutination Test (Rotales); Comparison with Electron Microscopy and Complement Fixation Test

A Study of Fixation for Electron Microscopy

Osmium tetroxide fixation of tissue blocks, as usually effected, is preceded by an acidification of the tissue. This acidification is probably responsible for morphological alterations which are notably disturbing in electron microscopy. The acidification and the resulting morphological alterations cannot be prevented by homogenizing the tissue directly in OsO(4) solutions or by adding enzyme i...

Sodium Permanganate Fixation for Electron Microscopy

Heightened interest in the cytology of certain free-living flatworms has been evident in the literature throughout the past year (5, 6, 10-12). The variety of problems dealt with by various investigators reflects the abundance of curious cellular specialization found in this group of animals. Moreover, the suitability of the Turbellarians for the study of regenerative processes is well recogniz...

Experiments on fixation for electron microscopy

The effect of fixation with a simple solution of osmium tetroxide in distilled water was studied by electron microscopy. Exocrine cells of the pancreas and cells of the proximal tubule of the kidney of the mouse were used as test-objects. Partially prepolymerized methacrylate was used for embedding. There did not appear to be any marked disorganization of the cell inclusions. The appearance of ...
