The purpose of the preface is to explain the book's objectives and how to use it; give warnings, disclaimers, and the like.* The main objective of Protein and Peptide Analysis by Mass Spec- trometry is quite straightforward-to present authoritative, up-to-date, and practical accounts of the use of mass spectrometry in the analysis of pep- tides and proteins. How to use it? Every reader will have their own particular interests and will surely be drawn toward the chapters that cover these interests. Within the remaining chapters, however, techniques are described with analytical possibilities...

The interest of investigators across a broad spectrum of scientific dis- plines has been steadily stimulated by the field of bacterial toxin research, an area that makes use of a large variety of biological, chemical, physicochemical, and medically oriented approaches. Researchers studying bacterial toxins need to be acquainted with all these disciplines in order to work effectively in the field. To date, there has been no published collection offering detailed descr- tions of the techniques and methods needed by researchers operating across the field'sdiverse areas. The present volume...

The observation that neuropeptide Y (NPY) is the most abundant peptide present in the mammalian nervous system and the finding that it elicits the most powerful orexigenic signal have led to active investigations of the properties of the NPY family of hormones, including peptide YY (PYY) and pancreatic polypeptide (PP). Nearly two decades of research have led to the identification of several NPY receptor subtypes and the development of useful receptor selective ligands. Moreover, these investigations have imp- cated NPY in the pathophysiology of a number of diseases, including feeding...

The potential now exists in many experimental systems to transfer a cloned, modified gene back into the genome of the host organism. In the ideal situation, the cloned gene is returned to its homologous location in the genome and becomes inserted at the target locus. This process is a controlled means for the repair of DNA damage and ensures accurate chromosome disjunction during meiosis. The paradigm for thinking about the mechanism of this p- cess has emerged primarily from two sources: (1) The principles of reaction mechanics have come from detailed biochemical analyses of the RecA protein...

Simian virus 40 gained notoriety in the 1960s because it was found to be a contaminant of polio and adenovirus vaccines that had been administered to millions of healthy individuals worldwide. The public health implications of this revelation provided the initial impetus for an in-depth study of SV40 biology. Later work showed that SV40 DNA sequences as well as infectious virus are in fact found in human tumors and may have contributed to oncog- esis. It also turned out that SV40 uses mostly cellular machinery to carry out many steps in viral infection, which makes it a powerful probe for...

Colin Graham and a team of leading investigators and expert clinical scientists update the acclaimed first edition with a collection of powerful, up-to-date PCR-based methods for DNA sequencing, many suitable for human genome sequencing and mutation detection in human disease. This second edition offers new material on automated DNA sequencers, capillary DNA sequencers, heterozygote mutation detection, web-based sequencing databases and genome sequencing sites, and the human genome project. State-of-the-art and highly practical, DNA Sequencing Protocols, 2nd Edn. constitutes an essential...

Interest in retinoic acid, the main biologically active derivative of vi- min A or retinol, increased dramatically between 1989 and 1993, following the cloning of nuclear receptors or RARs reported in 1987 (Fig. 1). Important discoveries since then have shown how RARs work as all-trans retinoic ac- dependent heterodimers with related nuclear receptors for 9-cis retinoic acid called RXRs. This has stimulated the development of synthetic analogs s- cific for each type of receptor, and opens the way to develop new methods for regulating pharmacologically the activity ofretinoic acid-dependent...

The aim of Plant Virology Protocols is to provide a source of infor- tion to guide the reader through the wide range of methods involved in gen- ating transgenic plants that are resistant to plant viruses. To this end, we have commissioned a wide-ranging list of chapters that will cover the methods required for: plant virus isolation; RNA extraction; cloning coat p- tein genes; introduction of the coat protein gene into the plant genome; and testing transgenic plants for resistance. The book then moves on to treatments of the mechanisms of resistance, the problems encountered with field...

A major mechanism by which cells regulate protein function is to place phosphate groups on serine and threonine residues. Though the steady-state level of protein phosphorylation depends on the relative activities of both kinases and phosphatases, a much greater effort has previously gone into the study of the former that the latter . Today, however, there is an increasing appreciation for the role that protein phosphatases play in the dynamic p- cess of protein phosphorylation . To date, there are four major types of protein serine/threonine phosphatase catalytic subunits, designated protein...

Gaining an understanding of the mechanisms by which cells process and respond to extracellular cues has become a major goal in many areas of bi- ogy and has attracted the attentions of almost every traditional discipline within the biological sciences. At the heart of these divergent endeavors are common methods that can aid biochemists, physiologists, and pharmacologists in ta- ling the specific questions addressed by their research. In Receptor Signal Transduction Protocols, a diverse array of meth- ologies employed to interrogate ligand--receptor and receptor-effector int- actions are...
