The Laboratory for Biological Ultrastructure

Facility Location

The Laboratory for Biological Ultrastructure,
University of Maryland, Department of Biology, Room 0240,
College Park, MD 20740

Brief Mission

The mission of the Laboratory is to provide a high quality, well equipped central biological electron imaging facility containing staff and a full complement of equipment for the successful preparation and imaging of a wide variety of biological sample types.     

The Laboratory will also serve as a training venue for faculty, post doctoral, graduate and undergraduate students, and outside investigators in the various techniques of biological electron microscopy.
