title: Modification of a scanning transmission electron microscope specimen holder for large section viewing.
abstract: A modification of a scanning transmission electron microscope specimen holder which permits full viewing of large plastic embedded tissue sections is discussed. The method for producing one-centimeter diameter "giant" grids is explained and the procedure for sample preparation is outlined. The modification aids the microscopist in his evaluation of tissue structural relationships by providing large areas of tissue for examination and reduces significantly the time required to prepare and examine standard 1-2 mm2 electron microscopy tissue sections. Light and electron microscopic evaluations can be made on the same tissue sections.
