Electron Microscopy


The Electron Microscopy core is a resource center for scanning and transmission electron microscopy providing investigators with consultation, service, and training. If ultra-thin sectioning and electron microscopy are needed, the staff can process the samples either by routine chemical fixation or high-pressure freezing and freeze-substitution methods and provide stained grids for subsequent imaging. The facility also offers negative-staining, immune-electron microscopy and assisted electron microscopy imaging.  For SEM imaging, the core has a desktop unit that is very easy to operate for samples needing magnification under 10,000x.
