Analytical Imaging Facility

Electron Microscopy

The Analytical Imaging Facility provides complete sample preparation utilizing a broad spectrum of techniques for examination by Transmission Electron Microscopy (TEM) or Scanning Electron Microscopy (SEM). Whether your interests lie in standard morphology or immunohistochemistry our staff will design protocols that will facilitate your experiments and optimize your results. Once the samples are processed, users can either work on the microscopes with one of our staff or independently (following training). Please see or contact one of our staff to plan a future experiment.
