The Electron Microscopy Core Facility of the National Heart Lung and Blood Institute (NHLBI) Division of Intramural Research (DIR), located on the Bethesda, MD campus of NIH, was established in June 2006. Our mission is to provide advice, technical services, training and use of facilities to NHLBI intramural scientists when aspects of their research require electron microscopy (EM) to answer specific 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 also offers training and use of its electron microscopes as well as collaboration on projects to scientists outside of the NHLBI. The facility is equipped with two 120kV transmission electron microscopes, including one equipped for computed electron tomography, one scanning electron microscope, as well as the preparative equipment for most biological EM applications.

There are no charges for consultation with NHLBI and NIDDK PIs to help design and plan experiments for use in the NHLBI EM Core.
All other consultation activities will be billed at a rate of $125/hr. Any appointment missed, late cancelled, or changed without 24-hour notice will result in a charge equal to the above-mentioned rate.
Therefore, we respectfully request at least 24-hour notice for cancellations or rescheduling of appointments.
All manuscripts containing data resulting from the use of this core must acknowledge the core in the acknowledgements section of the manuscript, or when appropriate, include core members as co-authors.
