Microscopy, Optical Spectroscopy and Macroscopic Techniques

About this book

This superb survey of the possible applications of physiochemical techniques to the analysis of biological macromolecules is designed for the practicing biochemist or biologist who wants to use the technique but lacks the experience. The contributors emphasize practical aspects, such as constraints on sample quantity, purity, and presentation; the problems of time and expense involved; the problems a technique is best suited to solve; and how the results may be interpreted. Among the methods examined are optical and infrared spectroscopy, microscopy, ultracentrifugation, calorimetry, X-ray and neutron scattering, and light scattering. This book will enable the reader to confidently collaborate with specialists in applying these techniques.
