A routine flat embedding method for electron microscopy of microorganisms allowing selection and precisely orientated...

A simple method is described to embed material in resin, in the form of microscope slides, to observe it with high resolution light microscopy, to select, orient and section it for TEM. This method can be applied to many kinds of material but is particularly useful for the study of rare or tiny plant or animal microorganisms from field or culture. A diamond scriber, translucent hydrosoluble resin release agent, translucent and smooth resin stubs and a longitudinally perforated block-holder for ultramicrotome are the specific tools of this method.
