The first book of its kind on marrow stromal cells, and written by leading experts in the field, this concise handbook aims to provide all that is needed to those new to this relatively young area of research. It provides a historical perspective and a summary of present knowledge of the marrow stromal lineages which are currently best understood. Detailed protocols for the isolation, culture and characterization of marrow stromal cell types from human and other animal species are given. The breadth and depth of the subject matter included makes the book equally suitable for new researchers and the more experienced investigator in this rapidly expanding field, including clinicians and bioscientists.

Everything you need to make the most of spot and screen tests

Spot Test Analysis demonstrates hundreds of valuable applications for the simple spot and screen test. Whether screening for cholesterol in blood, conducting antibody-based field tests for explosives, or even doing preliminary examinations, this laboratory reference book contains the detailed procedural information necessary for conducting rapid, on-the-spot chemical tests.

This new edition is revised and updated to provide the most useful information in the field. Among the important applications featured in this broad, far-reaching book are:

• Spot tests in clinical analysis
• Field and spot tests used in geochemistry and geochemical exploration
• Tests for detection and evaluation of air pollution
• Water quality screening for organic and inorganic materials
• Rapid screen tests of soils and plant tissues
• Screen tests for food adulteration and food composition

Spot Test Analysis, Second Edition is an indispensable resource for professionals in forensics, geochemistry, medicine, and public health.

Quick, inexpensive, and increasingly more sophisticated, the simple spot test has transformed the ways analysts screen for chemicals. In the past few decades, technological advancements have permitted enormous amplification of the resulting signal. This progression, coupled with a trend toward simplification, has enabled professionals in forensics, geochemistry, medicine, and public health to answer analytical questions with minimum cost and time.

Spot Test Analysis, Second Edition is a practical and far-reaching laboratory reference book. In addition to explaining the contemporary uses of spot and screen tests, this text describes the most up-to-date techniques for academic, medical, and commercial applications.

In this new edition, Dr. Ervin Jungreis provides detailed procedural information. While the screen and spot tests discussed here do not attempt to stand in for necessary complex analytical investigations, they do demonstrate that rapid methods are sufficient to register gross deviation from a norm and establish a conclusive negative.

This revised and updated Second Edition is as thorough in its treatment of techniques and applications as its predecessor. It provides many new wet and dry immunoassay procedures, such as tests for cholesterol and HDL, HIV and HSV, drugs, and explosives. Whole sections are devoted to spot testing in geochemistry, detecting toxins in air pollution, testing water for inorganic matter, and analyzing diagnostic test strips for foods, such as diethylene glycol in wine, saxitoxin in shellfish, and antibiotics in milk.

The investigation and manipulation of matter on the atomic scale have been revolutionized by scanning tunneling microscopy and related scanning probe techniques. This book is the first to provide a clear and comprehensive introduction to this subject. Beginning with the theoretical background of scanning tunneling microscopy, the design and instrumentation of practical STM and associated systems are described in detail, including topographic imaging, local tunneling barrier height measurements, tunneling spectroscopy, and local potentiometry. A treatment of the experimental techniques used in scanning force microscopy and other scanning probe techniques rounds out this section. The second part discusses representative applications of these techniques in fields such as condensed matter physics, chemistry, materials science, biology, and nanotechnology, so this book will be extremely valuable to upper-division students and researchers in these areas.

This is an extensively illustrated laboratory manual of transmission electron microscopy techniques for the technician, graduate student, or researcher. Chapters begin with a general discussion, move on to the chemicals and equipment required for the method being described and conclude with a step-by-step presentation of the method and instructions for the preparation of solutions. Notes at the end of each chapter warn of possible pitfalls and outline 'tricks of the trade'. The methods and techniques outlined have been tested for over ten years in clinical and research laboratory situations, and are entirely reliable. Practical Electron Microscopy covers fixation, dehydration and embedding, semi-thin and thin sectioning, the electron microscope, and photography. For this new edition, the chapters on photography and the electron microscope have been completely rewritten and two new chapters have been added, one on immuno electron microscopy using colloidal gold, and one dealing with such special techniques as retrieving specimens from paraffin and handling nasal brushings and blood samples. This manual will be an invaluable guide to anyone using electron microscopy on human and animal tissue and wishing to develop a routine that guarantees good and reproducible results.

The compound optical microscope, in its various modern forms, is probably the most familiar of all laboratory instruments and the electron microscope, once an exotic rarity, has now become a standard tool in biological and materials research. Both instruments are often used effectively with little knowledge of the relevant theory, or even of how a particular type of microscope functions. Eventually however, proper use, interpretation of images and choices of specific applications demand an understanding of fundamental principles. This book describes the principles of operation of each type of microscope currently available and of use to biomedical and materials scientists. It explains the mechanisms of image formation, contrast and its enhancement, accounts for ultimate limits on the size of observable details (resolving power and resolution) and finally provides an account of Fourier optical theory. Principles behind the photographic methods used in microscopy are also described and there is some discussion of image processing methods. The book will appeal to graduate students and researchers in the biomedical sciences, and it will be helpful to students taking a course involving the principles of microscopy.
