Hiroko Kubota,Muna Saleh,Jinny Menon%. In previous chapters of this volume, it has been discussed that cryofixation of almost pure water without ice formation and phase separation is a most difficult task. This explains why all attempts to make interactions of colloidal particles (“network formation”) visible by cryotechniques have ut

Gendered Inequities in the Academyspecimens (Nermut and Frank 1971; Kistler et al. 1977; Gross et al. 1985). Very thin specimens such as isolated membranes or isolated macromolecules can be directly adsorbed on carbon-coated grids. After rapid freezing, the grids are transferred into suitable high-vacuum equipment for freeze-drying

It is an unpleasant task to summarize the present situation and to arrive at the conclusion that these promises are only partly fulfilled. For the autoradiography of diffusible substances, there seem to be only practical limit

Gendered Inequities in the Academyponents (Plattner and Bachmann 1982). This intention of fixation is, of course, not restricted to applications in electron microscopy. Attempts to literally “freeze” the living structure by cryofixation can be traced back to the last century, and were extended to electron microscopy in its very earl

Margaret Kovach,Bonnie Stelmachprinciple, the irradiating electron beam (probe) is focussed on the area of interest in the specimen, while the secondary radiation (e.g. X-rays) generated by the interaction with the specimen is processed through a spectrometer to provide information on the kind and amount of the elements present.
