The Electron Microscopy (EM) Unit is dedicated to providing state-of-the-art technologies to support the ultrastructural imaging needs of NIAID scientists both in the Bethesda, Maryland, area and at the Rocky Mountain Laboratories in Hamilton, Montana.
The facility provides sample preparation and analysis ranging from basic to high resolution structural studies to immuno-localization of selected antigens for a wide array of specimens. A variety of methods, protocols, and equipment are employed to accommodate different preparative and imaging needs. Real-time viewing of samples by video image-sharing is available to NIAID users, enabling scientists at distant locations the ability to view samples simultaneously with microscopy staff.
