Single Molecule Biology

This handbook describes experimental techniques to monitor and manipulate individual biomolecules, including fluorescence detection, atomic force microscopy, and optical and magnetic trapping. It includes single-molecule studies of physical properties of biomolecules such as folding, polymer physics of protein and DNA, enzymology and biochemistry, single molecules in the membrane, and single-molecule techniques in living cells.

This is the first book solely devoted to single-molecule biochemistry and molecular biology. Authors were selected on the basis of their contribution to this new and exciting field, and were asked to focus more on the biological problems that can be approached using single-molecule techniques rather than on the techniques per se. It is thought that such techniques will eventually dominate the physical characterization of biologically important macromolecules.

Geared towards research scientists in structural and molecular biology, biochemistry, and biophysics, this manual will be useful to all who are interested in observing, manipulating and elucidating the molecular mechanisms and discrete properties of macromolecules.

Single molecule techniques, including single molecule fluorescence, optical tweezers, and scanning probe microscopy, allow for the manipulation and measurement of single biological molecules within a live cell or in culture. These approaches, amongst the most exciting tools available in biology today, offer powerful new ways to elucidate biological function, both in terms of revealing mechanisms of action on a molecular level as well as tracking the behaviour of molecules in living cells. This book provides the first complete and authoritative treatment of this rapidly emerging field, explicitly from a biological perspective. The contents are organized by biological system or molecule. Each chapter discusses insights that have been revealed about their mechanism, structure or function by single molecule techniques. Among the topics covered are enzymes, motor proteins, membrane channels, DNA, ribozymes, cytoskeletal proteins, and other key molecules of current interest. An introduction by the editor provides a concise review of key principles and an historical overview. The last section discusses applications in molecular diagnostics and drug discovery. * Organized by biological system or molecule. * Each chapter discusses insights into mechanism of action, structure, and function * Covers enzymes, motor proteins, membrane channels, DNA, ribozymes, etc. * Includes an introduction to key principles and an historical overview. * Discusses applications in molecular diagnostics and drug discovery. * Provides an expert's perspective on future developments.

Life scientists believe that life is driven, directed, and shaped by biomolecules working on their own or in concert. It is only in the last few decades that technological breakthroughs in sensitive fluorescence microscopy and single-molecule manipulation techniques have made it possible to observe and manipulate single biomolecules and measure their individual properties. The methodologies presented in Single Molecule Techniques: Methods and Protocols are being applied more and more to the study of biologically relevant molecules, such as DNA, DNA-binding proteins, and motor proteins, and are becoming commonplace in molecular biophysics, biochemistry, and molecular and cell biology. The aim of Single Molecule Techniques: Methods and Protocols is to provide a broad overview of single-molecule approaches applied to biomolecules on the basis of clear and concise protocols, including a solid introduction to the most widely used single-molecule techniques, such as optical tweezers, single-molecule fluorescence tools, atomic force microscopy, magnetic tweezers, and tethered particle motion. Written in the highly successful Methods in Molecular BiologyTM series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Single Molecule Techniques: Methods and Protocols serves as an ideal guide to scientists of all backgrounds and provides a broad and thorough overview of the exciting and still-emerging field of single-molecule biology.

Written by the leading experts in the field, this book describes the development and current state of the art in single molecule spectroscopy. The application of this technique, which started 1989, in physics, chemistry and biosciences is displayed.

Single-molecule experiments have provided freshperspectives on questions such as how proteins fold to specificconformations from highly heterogeneous structures, how signaltransductions take place on the molecular level, and how proteinsbehave in membranes and living cells.This volume is designed tofurther contribute to the rapid development of single-moleculebiophysics research. Filled with cutting-edge research reported in a cohesive mannernot found elsewhere in the literature, each volume of theAdvances in Chemical Physics series serves as the perfectsupplement to any advanced graduate class devoted to the study ofchemical physics.

In Single Molecule Studies of Proteins, expert researchers discuss the successful application of single-molecule techniques to a wide range of biological events, such as the imaging and mapping of cell surface receptors, the analysis of the unfolding and folding pathways of single proteins, the analysis interaction forces between biomolecules, the study of enzyme catalysis or the visualization of molecular motors in action. The chapters are aimed at established investigators and post-doctoral researchers in the life sciences wanting to pursue research in the various areas in which single-molecule approaches are important; this volume also remains accessible to advanced graduate students seeking similar research goals.
