Imaging Cores - Electron



ICEL research, education and collaboration activities between July 1, 2021 and May 1, 2023.


 The Imaging Cores - Electron is a unique full-service lab at the University of Arizona, providing access to advanced expertise in Biological Transmission Electron Microscopy (TEM) to support basic and translational research, from consultation to high-resolution imaging, data analysis and interpretation. The core facility house the FEI Tecnai G2 Spirit BT transmission electron microscope and several ultramicrotomes, enabling investigators the ultrastructural evaluation and analysis of biological and non-biological samples, serving the academy and industry.


 The core facility provides access to hands-on TEM instrument and ultramicrotomy training. From a total of 86 users, 54.35 % training and assisted use were provided to graduate students, postdoctoral fellow, research staff and  faculty. 


 Two grants were supported.
