The Electron Microscopy Facility (CAP/CLIA certified) provides a variety of electron microscopy services for clinical and research use. These include tissue processing and embedding, preparation of one micron thick toluidine blue stained sections and routine transmission electron microscopy for cell culture and tissue specimens.

Both the JEOL 1200EX and JEOL JEM1400 electron microscopes in the facility have high resolution CCD based cameras for high quality digital imaging. The clinical digital images of renal biopsies are collected and uploaded into password protected online clinical reports. Research images will be available for downloading by individual investigators as part of a password protected online system.


Service available to: All entities, including for-profit organization

Priority service given to: Members of the Diabetes Research and Training Center and to members of the Department of Pathology & Immunology.

Request services

Contact Robert Schmidt or Karen Green at kareng@wustl.edu or 314-362-7462. Investigators are strongly encouraged to discuss their experimental design and individual needs in advance of harvesting tissue/cultured cells from an experiment in order to optimize methods of analysis. Pricing will be discussed for services provided at the time they are scheduled.
