Electron Microscopy
Electron Microscopy prepares and images specimens by transmission or scanning EM and can also do two- and three-dimensional image processing. The lab specializes in biological EM, but also works with non-biological samples. The EM Core Lab can train users in sample preparation, microscope use, and image analysis. Common EM procedures done in the lab include thin-sectioning, negative staining, and cryogenic EM (cryo-EM).

Charge Rates Procedure / Federal Facilities and Administration (F&A) Rate
Part of the University’s agreement with the Federal Government regarding F&A is that the University will not offer a lower than F&A rate to other kinds of sponsors. That means that the University has to use, at minimum, the same rates for commercial sponsors as it does for the Federal Government. The University would jeopardize its relationship with the Federal Government (the University’s single largest sponsor) if it were to accept rates lower than the current federal F&A rate.
The current F&A Rate is: 54%
The facility internal rate is used when exclusively internal funding sources are used. The F&A / external academic rate applies when external funding sources are used i.e. Federal Government or other academic universities. For more information about F&A rates at the University of Utah please see: 6.3 Indirect Costs/Facilities and Administrative Costs (F&A)
