introduction
The Electron Microscope (EM) laboratory was established in the year 1971 in the Department of Anatomy of All India Institute of Medical Science (AIIMS). Recognizing the contribution of the laboratory and the need for the ultrastructural investigations, the Department of Science and Technology (DST), Government of India established a Regional Electron Microscope facility in 1983 at AIIMS under its RSIC/SIF program. This center is presently known as Sophisticated Analytical Instrument Facility (SAIF) – AIIMS, New Delhi, under the SAIF Program of DST.
