What We Do

The Electron Microscopy Facility enables biological research at micro- and nano-scales and provides Janelia researchers a nexus for multidisciplinary collaboration in high-resolution imaging. We offer state-of-the-art instrumentation, services, and training in sample preparation, transmission  electron microscopy and image analysis.  With 5,000-square-feet of space, we’re set up to prepare samples using conventional wet chemistry, microwave techniques and high-pressure freezing/freeze substitution. Our skilled staff will assist researchers and train them in the science and practice of electron microscopy as well.

  • FEI Tecnai Spirit BioTWIN trasmission electron microscope with LaB6 gun and Gatan Oneview camera
  • Zeiss Xradia 510 Versa for submicron X-ray imaging
  • Delphi integrated scanning electron microscope and fluorescence microscope
  • Wohlwend HPF Compact 03 high-pressure freezer
  • Leica EM ICE high pressure freezer
  • Leica EM AFS2 automatic freeze-substitution system for processing samples prepared by high-pressure freezing or progressive lowering of temperature (PLT) methods
  • Built-in UV lamp for UV-catalyzed resin polymerization at low temperature
