Increasing numbers of physicists, chemists, and mathematicians are moving into biology, reading literature across disciplines, and mastering novel biochemical concepts. To succeed in this transition, researchers must understand on a practical level what is experimentally feasible. The number of experimental techniques in biology is vast and often specific to particular subject areas; nonetheless, there are a few basic methods that provide a conceptual underpinning for broad application. Introduction to Experimental Biophysics is the ideal benchtop companion for physical scientists interested in getting their hands wet. Assuming familiarity with basic physics and the scientific method but no previous background in biology or chemistry, this book provides: A thorough description of modern experimental and analytical techniques used in biological and biophysical research Practical information and step-by-step guidance on instrumentation and experimental design Recipes for common solutions and media, lists of important reagents, and a glossary of biological terms used Developed for graduate students in biomedical engineering, physics, chemical engineering, chemistry, mathematics, and computer science, Introduction to Experimental Biophysics is an essential resource for scientists to overcoming conceptual and technical barriers to working in a biology wet lab.
The propagation of signals through the nervous system depends on rapid changes in electric potential across cell membranes. These changes are mediated by ion channels--macromolecular pores that facilitate the passage of specific ions (e.g., K+ or Na+) through cell membranes in response to various signals. Defects in ion channels can lead to diseases such as epilepsy. This laboratory manual provides state-of-the-art techniques for investigating ion channel properties and activity, particularly in the nervous system. Contributors present electrophysiological methods to examine single-channel activity in cultured cells, to study synaptic plasticity and circuit dynamics in brain slice preparations, and to perform whole-cell recordings in awake--and even freely moving--animals. The use of optogenetic tools to study synapses or small networks in organotypic slice cultures is also covered. Many of the experimental setups described can be adapted for other ion channels, cell types, or systems. The manual includes background on the structure, function, and regulation of different voltage- and ligand-gated ion channels. Therefore, it is a useful resource for all cell biologists and neuroscientists seeking to further understand the complex roles of ion channels in normal physiology and disease.
All living matter is comprised of cells, small compartments isolated from the environment by a cell membrane and filled with concentrated solutions of various organic and inorganic compounds. Some organisms are single-cell, where all life functions are performed by that cell. Others have groups of cells, or entire organs, specializing in one particular function. The survival of the entire organism depends on all of its cells and organs fulfilling their roles. While the cells are studied by different sciences, they are seen differently by biologists, chemists, or physicists. Biologists concentrate their attention on cell structure and function. What does the cell consist of? Where are its organelles? What function does each organelle fulfil? From a chemists' point of view, a cell is a complex chemical reaction chamber where various molecules are synthesized or degraded. The main question is how these, sometimes very complicated chains of reactions are controlled. Finally, from a physics standpoint, one of the main questions is the physical movement of all these molecules between organelles within the cell, as well as their exchange with the extracellular medium. The aim of this book is to look into the basic physical phenomena occurring in cells. These physical transport processes facilitate chemical reactions in the cell and that in turn leads to the biological functions necessary for the cell to satisfy its role in the mother organism. Ultimately, the goals of every cell are to stay alive and to fulfil its function as a part of a larger organ or organism. This book is an inventory of physical transport processes occurring in cells while the second volume will be a closer look at how complex biological and physiological cell phenomena result from these very basic physical processes.
A richly illustrated undergraduate textbook on the physics and biology of light Students in the physical and life sciences, and in engineering, need to know about the physics and biology of light. Recently, it has become increasingly clear that an understanding of the quantum nature of light is essential, both for the latest imaging technologies and to advance our knowledge of fundamental life processes, such as photosynthesis and human vision. From Photon to Neuron provides undergraduates with an accessible introduction to the physics of light and offers a unified view of a broad range of optical and biological phenomena. Along the way, this richly illustrated textbook builds the necessary background in neuroscience, photochemistry, and other disciplines, with applications to optogenetics, superresolution microscopy, the single-photon response of individual photoreceptor cells, and more. With its integrated approach, From Photon to Neuron can be used as the basis for interdisciplinary courses in physics, biophysics, sensory neuroscience, biophotonics, bioengineering, or nanotechnology. The goal is always for students to gain the fluency needed to derive every result for themselves, so the book includes a wealth of exercises, including many that guide students to create computer-based solutions. Supplementary online materials include real experimental data to use with the exercises. Assumes familiarity with first-year undergraduate physics and the corresponding math Overlaps the goals of the MCAT, which now includes data-based and statistical reasoning Advanced chapters and sections also make the book suitable for graduate courses An Instructor's Guide and illustration package is available to professors
Phage-display technology has begun to make critical contributions to the study of molecular recognition. DNA sequences are cloned into phage, which then present on their surface the proteins encoded by the DNA. Individual phage are rescued through interaction of the displayed protein with a ligand, and the specific phage is amplified by infection of bacteria. Phage-display technology is powerful but challenging and the aim of this manual is to provide comprehensive instruction in its theoretical and applied so that any scientist with even modest molecular biology experience can effectively employ it. The manual reflects nearly a decade of experience with students of greatly varying technical expertise andexperience who attended a course on the technology at Cold Spring Harbor Laboratory. Phage-display technology is growing in importance and power. This manual is an unrivalled source of expertise in its execution and application.
Introductory Experiments on Biomolecules and their Interactions provides a novel approach to teaching biomolecules in the lab. While featuring the requisite fundamentals, it also captures the author's experience in industry, thus providing unique, up-to-date experiments which take the learning experience one-step further. The text parallels lectures using a standard biochemistry undergraduate text. Unlike most current lab manuals available in the market which simply emphasize an introduction of techniques, this lab manual provides students with opportunities to demonstrate and prove the knowledge and theories they learn from class. - Features quantitative analysis of RNA degradation by RNase - Contains problem sets, calculations, and references for each lab fully immersing students in the learning process - Includes instruction on how to maintain a lab notebook and write a formal lab report - Provides hands-on engagement with the four major types of biomolecules and "real-life and better applied examples of molecular interactions
A physicist's guide to the phenomena of life Interactions between the fields of physics and biology reach back over a century, and some of the most significant developments in biology—from the discovery of DNA's structure to imaging of the human brain—have involved collaboration across this disciplinary boundary. For a new generation of physicists, the phenomena of life pose exciting challenges to physics itself, and biophysics has emerged as an important subfield of this discipline. Here, William Bialek provides the first graduate-level introduction to biophysics aimed at physics students. Bialek begins by exploring how photon counting in vision offers important lessons about the opportunities for quantitative, physics-style experiments on diverse biological phenomena. He draws from these lessons three general physical principles—the importance of noise, the need to understand the extraordinary performance of living systems without appealing to finely tuned parameters, and the critical role of the representation and flow of information in the business of life. Bialek then applies these principles to a broad range of phenomena, including the control of gene expression, perception and memory, protein folding, the mechanics of the inner ear, the dynamics of biochemical reactions, and pattern formation in developing embryos. Featuring numerous problems and exercises throughout, Biophysics emphasizes the unifying power of abstract physical principles to motivate new and novel experiments on biological systems. Covers a range of biological phenomena from the physicist's perspective Features 200 problems Draws on statistical mechanics, quantum mechanics, and related mathematical concepts Includes an annotated bibliography and detailed appendixes
