| EM Suite Services |
| The Electron Microscopy Suite provides services and expertise in all aspects of electron microscopy.
Services include conventional fixation and sectioning of cells and tissues, negative staining of organelles and macromolecular assemblies, shadowing of isolated protein molecules, immunolabeling, etc. Expert consultation on all aspects of experimental planning and micrograph interpretation is provided by the facility director, Dr. Charles Ribak Services Include: Fixation and Sectioning Negative Staining Immuno-Electron Microscopy Fixation and Sectioning Conventional fixation and sectioning of cells and tissues. Tissues, organelles, cell cultures, etc. are fixed with aldehydes and osmium tetroxide, dehydrated through a graded series of alcohol to remove water, and finally embedded in a plastic resin. The resin-embedded material is sectioned using either glass or diamond knives. Sections can be either cut thick (0.5 to several micrometers) for light microscopy or ultrathin (60 to 90 nm) for conventional transmission electron microscopy. |
