Description: In biomedical research, because of a dramatic increase in productivity, immunocytochemistry has emerged as a major technique. The proposed book will provide the first practical guide to planning, performing, and evaluating immunocytochemical experiments. In today’s graduate education the emphasis is on doing research and not on formal class work. Graduate students therefore lack the background in many essential techniques necessary to perform research in fields in which they were not trained. As director of a university core microscopy facility which sees students and faculty from dozens of laboratories each year, Dr. Burry has surmised the vast majority of these novice microscope users need considerable help. In an attempt to educate users, Dr. Burry has initiated immunocytochemistry seminars and workshops which serve to train people in this powerful research tool. The proposed book is an outgrowth of these presentations and conversations with, by now, hundreds of people who have asked for help. The philosophy which separates this book from other books in this field is that it is practical, rather than academic. In looking at other important immunocytochemistry titles, the predominant orientation is academic, with the author attempting to comprehensively discuss the topic. For example, one book with sample preparation lists ten fixatives which can be used; however, only two such fixatives are commonly used today. In this particular title, the detailed discussion of old methods might be seen as important in establishing the author as an expert. By contrast, the approach for Burry’s book would be to discuss methods based on what works in animal research laboratories today, and focus only on the most productive methods. An additional distinction with this proposed book is the focus on animal research and not human pathology. There is a certification program for pathology technicians which requires them to learn a set body of material based on processing human tissue for examination by a pathologist. Many of the books on immunocytochemistry aim at this large pathology user base. Due to historical reasons, pathology laboratories process human tissues in a specific way and embed the tissue in paraffin, as has been done for over a century. In the last ten years, the power of immunocytochemistry in clinical diagnosis has become clear and has accordingly been adapted to pathology. However, the extensive processing needed for paraffin sections is not needed if the tissues are from research animals. Processing for animal-based tissues takes about a third of the time and results in higher quality images. The focus of this book is on processing these animal research tissues for immunocytochemistry. Today, there are no technique books which are aimed at this user base. As a subject matter expert in the area of the proposed book, Dr. Burry will make recommendations and offer opinions. Because this field is new and is emerging, there are numerous advantages of specific methods over other, more generalized methods. The purpose of this book is to show a novice how to do immunocytochemistry without engaging in a discussion of possible advanced methods. For the advanced user, there are several good books which discuss the unusual methods, yet for the novice there are currently none. Main Author : Richard W. Burry, The Ohio State University (United States). The Outline of the Book : Each chapter supplies a set of important principals and steps necessary for good immunocytochemistry. The information is distilled down to include only the most important points and does not attempt to cover infrequently used procedures or reagents. At the end of most chapters is a section on trouble-shooting many of the common problems using the Sherlock Holmes method. Each chapter also includes specific protocols which can be used. The goal of each chapter is to present the reader with enough information to successfully design experiments and solve many of the problems one may encounter. Using immunocytochemical protocols without the understanding of their workings is not advised, as the user will need to evaluate his or her results to determine whether the results are reliable. Such evaluation is extremely important for users who need reliable images which will clearly answer important scientific questions. 1.

Immunohistochemistry and immunocytochemistry are invaluable tools for the visualization of tissue and cellular antigens in diagnostic and biological research environments. The need to obtain accurate, reliable and reproducible results is paramount. It is with this fundamental aim in mind that we have compiled Immunohistochemistry: Essential Methods. We have achieved this by examining each aspect of immunochemistry in turn, with each chapter including detailed information regarding the subject matter in question. Each chapter is written by an expert in their field and includes protocols that are typically used in their own research. Subjects covered are, amongst others, antibodies and their production; selection of reporter labels; immunochemical staining methods and experimental design (both using single and multiple reporter labels); quality assurance; automated immunochemistry; confocal microscopy and electron microscopy. In addition, benefits and limitations of each approach are discussed within the chapters.

Electron microscopy in the biological sciences can be divided into two disciplines. The first, concerned with high resolution detail of particles or periodic structures, is mostly based on sound theoretical principles of physics. The second, by far the larger discipline, is interested in the information obtainable from thin sections. The theoretical back ground to those groups of techniques for preparing and looking at thin sections is often inexact and "loose", for want of a better word. What should be chemistry is often closer to alchemy. This kind of electron microscopy is often enshrined with mystical recipes, handed down from generation to generation. Admittedly, many of the processes involved, such as those required to embed tissue in epoxy resins, involve multiple interconnected steps, which make it difficult to follow the details of anyone of these steps. If all these steps are shrouded in some mystery, however, can one really trust the final image that emerges on the EM screen? When we present the data in some semi quantitative form is there really no better way to do it than to categorize the parameters with ++, +/-, etc? What happens when one labels the sections with antibodies? Does the whole business necess arily need to be more of an "art" than a "science"? Upon reflecting on these problems in 1981, I had the impression that many of the multi-authored textbooks that existed then (and that have appeared since) tended to exacerbate or at least perpetuate this

This volume provides a comprehensive reference guide for researchers to study the applications of labeled antibodies. Chapters guide reader through the theory and practice of immunohistochemistry, immunocytochemistry and immunofluorescence techniques. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and useful tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Immunohistochemistry and Immunofluorescence: Methods and Protocols aims to be a useful practical guide to scientists to help further their study in this field

Since antibodies tagged with markers have been developed, immunocytochemistry has become an important method for identifying tissue substances and the localisation of nucleic acid in tissue by in situ hybridisation in molecular biology. This laboratory book covers the embedding of tissue using less sensitive epoxy resin methods to the more sensitive procedures employing the acrylics. The possibilities are discussed and results are presented so that an understanding of the techniques can be acquired.

Immunocytochemistry and in situ hybridization are widely used biomedical sciences. They are essential in medical diagnosis and in cell biology research. Affinity labeling is the central goal of the experimental strategy involving a series of techniques in a logical order; from the effects of specimen fixation, through specimen preparation to expose the antigen, to optimizing immunolabeling, to assessing the result and finally to safety considerations. Numerous examples of these techniques in biomedical sciences are included, as well as experimental assays and practical tips. This survey of methods will serve as an invaluable reference source in any laboratory setting (academic, industrial or clinical) involved in research in almost every branch of biology or medicine, as well as in pharmaceutical, biotechnological and clinical applications.

Immunocytochemistry is classically defined as a procedure to detect antigens in cellular contexts using antibodies. However, over the years many aspects of this procedure have evolved within a plethora of experimental setups. There are different ways to prepare a given specimen, different kinds of antibodies to apply, different techniques for imaging, and different methods of analyzing the data. In this book, various ways of performing each individual step of immunocytochemistry in different cellular contexts are exemplified and discussed. Applications of Immunocytochemistry offers technical and background information on different steps of immunocytochemistry and presents the application of this technique and its adaptations in cell lines, neural tissue, pancreatic tissue, sputum cells, sperm cells, preimplantation embryo, arabidopsis, fish gonads, and Leishmania.
