Scope of the Core Facility
The Facility is dedicated to providing the scientific community within NINDS equipment for transmission electron microscopy . The Facility also offers expertise in the use and application of microscopy to a wide variety of scientific problems. Highly competent technical staff provide all users access to routine as well as customized protocols involving fixation, embedding, sectioning and examination of samples. Pre- and Post-embed labeling procedures are available.
