Imaging Cores - Electron



Overview of Services

Electron Microscopy

The Imaging Cores - Electron facility provides full Biological Transmission Electron Microscopy (TEM) related research, consultation, and imaging services to faculty, scientists and students at the University of Arizona campus, external research institutions and industrial community.

In the Core Facility, we receive fixed samples for TEM preparation, negative staining and immunoelectron microscopy techniques, ultramicrotomy (thick resin sections suitable for light microscopy and ultrathin sections for TEM), digital imaging and interpretation of results. We are also available to support you in planning for future experiments, writing grants, publications and collaborations.

Individual training is available to the users interested in operating the FEI Tecnai G2 Spirit BT transmission electron microscope to obtain their own images and the ultramicrotomes to section their samples upon request.

Acknowledging the Imaging Cores - Electron:

In the core facility, we provide access to instrumentation, services and guidance to users' research. Proper acknowledgement of the core and staff serves as a metric for assessing the performance of the facility and to ensure and impact financial support for operations and expansion from the UA administration. Please acknowledge the core and the staff in your publications accordingly, using the following verbiage:

University of Arizona Imaging Cores - Electron Core Facility RRID:SCR_023279


Note: As of February 1, 2022 the optical microscopy aspect of this core was rolled into Imaging Cores – Marley, which was re-named Imaging Cores - Optical. No optical microscopes or workstations were physically moved from their current locations, the imaging cores were simply re-aligned and re-named around their functions rather than their locations. IC-Optical operates in the Marley and Life Sciences North buildings with the same personalized service that you have come to expect from Patty Jansma and Doug Cromey.
