A Safety Considerations Many techniques described here involve a number of hazards, such as high electrical current and voltage, radioactivity and highly toxic chemicals. It is absolutely essential that the instructions of equipment manufacturers be followed, and that particular attention be paid to the local and federal safety regulations. B Introduction The expression of prokaryotic and eukaryotic genes has been shown most often to be regulated at the level of mRNA synthesis. Thanks to the rapid development of methods for dissecting DNA sequences, cis-acting regulatory elements such as promoters and enhancers have been recognised. More recently, the widely expressed intuition that discrete sequences within these elements constitute binding sites for sequence-specific binding proteins has been confirmed, especially through the use of "footprinting" assays (for examples, Galas and Schmitz, 1978). This and similar assays have already resulted in the recognition, isolation and analysis of DNA-bind ing proteins for several genes. Excellent reviews exist of the structural studies on these transcription regulatory proteins and related DNA elements (for example, Glover, 1989 and Johnson and McKnight, 1989), to which the reader is referred for detailed information. To set the scene for applications of the techniques described in this volume, only the barest outline of previous studies is presented here. Protein-DNA interactions are dependent on very specific tertiary configurations of the binding protein which allow the closest contact with the DNA helix.

So much has been learned about RNA in the past ten years that the ability to purify, analyze, and manipulate RNA molecules is now essential in all kinds of bioscience. Initiating RNA research can be intimidating but the new book RNA: A Laboratory Manualprovides a broad range of up-to-date techniques presented in a functional framework, so that any investigator can confidently handle RNA and carry out meaningful experiments, from the most basic to the highly sophisticated. Originating in three of the field's most prominent laboratories, this manual provides the necessary background and strategies for approaching any RNA investigation, as well as detailed protocols and extensive tips and troubleshooting information. It is required reading for every research laboratory in the life sciences.

This laboratory guide represents a growing collection of tried, tested and optimized laboratory protocols for the isolation and characterization of eukaryotic RNA, with lesser emphasis on the characterization of prokaryotic transcripts. Collectively the chapters work together to embellish the RNA story, each presenting clear take-home lessons, liberally incorporating flow charts, tables and graphs to facilitate learning and assist in the planning and implementation phases of a project.RNA Methodologies, 3rd edition includes approximately 30% new material, including chapters on the more recent technologies of RNA interference including: RNAi; Microarrays; Bioinformatics. It also includes new sections on: new and improved RT-PCR techniques; innovative 5' and 3' RACE techniques; subtractive PCR methods; methods for improving cDNA synthesis.* Author is a well-recognized expert in the field of RNA experimentation and founded Exon-Intron, a well-known biotechnology educational workshop center * Includes classic and contemporary techniques * Incorporates flow charts, tables, and graphs to facilitate learning and assist in the planning phases of projects

Here is the most complete guide available to the isolation, analysis, and synthesis of RNA. It covers everything researchers and laboratory workers need to know about the study of gene expression via RNA analysis-from the theory behind the methods, to actual problem-solving techniques. Step-by-step protocols are presented for each method. A careful presentation of the experimental formalities of these protocols enables specialists and nonspecialists alike to implement the methods easily in the laboratory. Each protocol is accompanied by the theoretical background underlying the experimental procedure and most chapters contain illustrations of typical results and troubleshooting tips. A Laboratory Guide to RNA offers a straightforward detailed account of experimental procedures, ranging from the isolation of RNA from a variety of cell and tissue types, detection analysis, and quantitation using a range of strategies, to large- and small-scale synthesis of RNA. This unique guide not only covers established procedures such as RNA blotting and nuclease protection, but also the latest protocols for quantitative PCR and differential display. Protocols addressing in situ hybridization are highlighted in an eight-page, full-color section that illustrates the power of the technique for detection of gene expression in tissues and whole organisms. Featuring contributions from leading research laboratories and the biotechnology field, A Laboratory Guide to RNA: Isolation, Analysis, and Synthesis provides all the methods required for RNA analysis. It is the ideal laboratory guide for research scientists, graduate students, and lab personnel who need a solid reference on the analysis of gene expression at the RNA level.

Never before has there been such a comprehensive book of protocols. This compendium offers a full range of research techniques-from cell culture, to biochemical, to microscopic and genetic. More focused books, like Cold Spring Harbor's Manipulating the Mouse Embryo, are similar though more narrow in scope. This book will appeal to a broad range of researchers, from basic experimental scientists to clinical and animal scientists.
