Electron Microscopy Core

The Electron Microscopy Core Facility provides advice, technical services, training and use of facilities to NHLBI intramural investigators who require electron microscopy (EM) to answer specific research questions. In general, this refers to questions involving subcellular, supramolecular or macromolecular structure at a level of resolution below that of the light microscope.

The facility is equipped with two 120kV transmission electron microscopes and one scanning electron microscope as well as the preparative equipment for most biological EM applications. One transmission electron microscope is a current model equipped for electron tomography and automated montage acquisition.
