Book Description
Electron Microscopy Methods and Protocols is designed for the established researcher as a manual for extending knowledge of the field. It is also for the newcomer who wishes to move into the field. A wide range of applications for the examination of cells, tissues, biological macromolecules, molecular structures, and their interactions are discussed. We have tried to gather together methods that we consider to be those most generally appli- ble to current research in both cell and molecular biology. Each chapter c- tains a set of related practical protocols with examples provided by experts who have first-hand knowledge of the techniques they describe. The individual chapters are grouped according to similarities in their specimen preparation and methodology. Methods are presented in detail, in a step-by-step fashion, using reproducible protocols the authors have personally checked. During the last decade, the scientific literature describing the use of colloidal gold as an immunocytochemical marker has increased at an ex- nential rate, and this trend is expected to continue. We have included a large number of variations on the immunogold labeling technique. In both the ne- tive staining and cryo chapters, authors emphasize the “immunological app- cations” in order to correlate as fully as possible with the emphasis on immunogold labeling in the other chapters. Electron Microscopy Methods and Protocols commences with the routine preparation of biological material for classical transmission electron microscopy involving tissue fixation, embedding, and sectioning (Chap. 1).

Book Description
To preserve tissue by freezing is an ancient concept going back pre sumably to the practice of ice-age hunters. At first glance, it seems as simple as it is attractive: the dynamics of life are frozen in, nothing is added and nothing withdrawn except thermal energy. Thus, the result should be more life-like than after poisoning, tan ning and drying a living cell as we may rudely call the conventional preparation of specimens for electron microscopy. Countless mishaps, however, have taught electron microscopists that cryotechniques too are neither simple nor necessarily more life-like in their outcome. Not too long ago, experts in cryotechniques strictly denied that a cell could truly be vitrified, i.e. that all the solutes and macro molecules could be fixed within non-crystalline, glass-like solid water without the dramatic shifts and segregation effects caused by crystallization. We now know that vitrification is indeed pos sible. Growing insight into the fundamentals of the physics of water and ice, as well as increasing experience of how to cool cells rapidly enough have enlivened the interest in cryofixation and pro duced a wealth of successful applications.

Book Description
The frozen-hydrated specimen is the principal element that unifies the subject of low temperature microscopy, and frozen-hydrated specimens are what this book is all about. Freezing the sample as quickly as possible and then further preparing the specimen for microscopy or microanalysis, whether still embedded in ice or not: there seem to be as many variations on this theme as there are creative scientists with problems of structure and composition to investigate. Yet all share a body of com mon fact and theory upon which their work must be based. Low-Temperature Micros copy and Analysis provides, for the first time, a comprehensive treatment of all the elements to which one needs access. What is the appeal behind the use of frozen-hydrated specimens for biological electron microscopy, and why is it so important that such a book should now have been written? If one cannot observe dynamic events as they are in progress, rapid specimen freezing at least offers the possibility to trap structures, organelles, macro molecules, or ions and other solutes in a form that is identical to what the native structure was like at the moment of trapping. The pursuit of this ideal becomes all the more necessary in electron microscopy because of the enormous increase in resolution that is available with electron-optical instruments, compared to light optical microscopes.

Book Description
In 1939, when the electron optics laboratory of Siemens & Halske Inc. began to manufacture the first electron microscopes, the biological and medical profes sions had an unexpected instrument at their disposal which exceeded the reso lution of the light microscope by more than a hundredfold. The immediate and broad application of this new tool was complicated by the overwhelming prob lems inherent in specimen preparation for the investigation of cellular struc tures. The microtechniques applied in light microscopy were no longer appli cable, since even the thinnest paraffin layers could not be penetrated by electrons. Many competent biological and medical research workers expressed their anxiety that objects in high vacuum would be modified due to complete dehydration and the absorbed electron energy would eventually cause degrada tion to rudimentary carbon backbones. It also seemed questionable as to whether it would be possible to prepare thin sections of approximately 0. 5 11m from heterogeneous biological specimens. Thus one was suddenly in posses sion of a completely unique instrument which, when compared with the light microscope, allowed a 10-100-fold higher resolution, yet a suitable preparation methodology was lacking. This sceptical attitude towards the application of electron microscopy in bi ology and medicine was supported simultaneously by the general opinion of colloid chemists, who postulated that in the submicroscopic region of living structures no stable building blocks existed which could be revealed with this apparatus.

Book Description
Plants, fungi, and viruses were among the first biological objects studied with an electron microscope. One of the two first instruments built by Siemens was used by Helmut Ruska, a brother of Ernst Ruska, the pioneer in constructing electron microscopes. H. Ruska published numerous papers on different biological objects in 1939. In one of these, the pictures by G. A. Kausche, E. Pfankuch, and H. Ruska of tobacco mosaic virus opened a new age in microscopy. The main problem was then as it still is today, to obtain an appropriate preparation of the specimen for observation in the electron microscope. Beam damage and specimen thickness were the first obstacles to be met. L. Marton in Brussels not only built his own instrument, but also made considerable progress in specimen preparation by introducing the impregnation of samples with heavy metals to obtain useful contrast. His pictures of the bird nest orchid root impregnated with osmium were revolutionary when published in 1934. It is not the place here to recall the different techniques which were developed in the subsequent years to attain the modern knowledge on the fine structure of plant cells and of different plant pathogens. The tremendous progress obtained with tobacco mosaic virus is reflected in the chapter by M. Wurtz on the fine structure of viruses in this Volume. New cytochemical and immunological techniques considerably surpass the morphological information obtained from the pathogens, especially at the host-parasite interface.

Book Description
This volume of this acclaimed series deals with electron microscopic techniques applied for the elucidation of microbial structures and structure-function relationships at cellular, sub-cellular, and macromolecular levels. Many of the recent findings on ultrastructural features of microorganisms have been obtained with newly developed methods, though classical approaches have not lost their validity. Therefore, both conventional and new methods have been incorporated into this volume. The topics dealt with are meaningful not only in bacterial cytology but also in physiology, enzymology, biochemistry, and molecular biology, and include aspects of medical and biotechnological application.

Book Description
This book contains all the necessary information and advice for anyone wishing to obtain electron micrographs showing the most accurate ultrastructural detail in thin sections of any type of biological specimen. The guidelines for the choice of preparative methods are based on an extensive survey of current laboratory practice. For the first time, in a textbook of this kind, the molecular events occurring during fixation and embedding are analysed in detail. The reasons for choosing particular specimen preparation methods are explained and guidance is given on how to modify established techniques to suit individual requirements. All the practical methods advocated are clearly described, with accompanying tables and the results obtainable are illustrated with many electron micrographs.

Book Description
This book describes the capabilities of nuclear techniques for elemental microanalysis in the biological field. A description of basic principles is given at the beginning, with special emphasis on X-ray Fluorescence, Rutherford Backscattering Spectrometry, Nuclear Reaction Analysis and Scanning Transmission Ion Microscopy. The major part of the volume is devoted to the applications in the life sciences and presents a general review of the subjects investigated during the last fifteen years. In addition, technical aspects of nuclear microanalysis in living tissues, including data processing and specimen preparation, are detailed. Examples of recent applications in cellular pharmacology, cell physiology and biomedicine are presented. The last part concerns the studies of unicellular micro-organisms involved in pollution problems. Postgraduate students and confirmed scientists will be able to find here basic information, references and practical aspects of this new tool, with in each case a comparison with other analytical techniques.
