Book Description
Hans Neurath has written that this is the second golden era of enzymology {Protein Science [1994], vol. 3, pp. 1734—1739); he could with justice have been more general and referred to the second golden age of protein chemistry. The last two decades have seen enormous advances in our understanding of the structures and functions of pro teins arising on the one hand from improvements and developments in analytical techniques {see the companion volume, Basic Protein and Peptide Protocols, in this series) and on the other hand from the tech nologies of molecular genetics. Far from turning the focus away from protein science, the ability to isolate, analyze, and express genes has increased interest in proteins as gene products. Hence, many laborato ries are now getting involved in protein isolation for the first time, either as an essential adjunct to their work in molecular genetics or because of a curiosity to know more about the products of the genes that they have been studying. Protein Purification Protocols is aimed mainly at these newcom ers to protein purification, but it is hoped that it will also be of value to established practitioners who may find here techniques that they have not tried, but which might well be most applicable in their work. With the exception mainly of the first and last chapters, the format of the contributions to the present book conform to the established format of the Methods in Molecular Biology series.

Book Description
A Laboratory Manual of Analytical Methods of Protein Chemistry (Including Polypeptides), Volume 1: The Separation and Isolation of Proteins deals with the techniques used in the separation and isolation of proteins, including fractionation and characterization by dialysis, multi-membrane electrodecantation, and zonal density gradient electrophoresis. The fractionation of proteins by adsorption and ion exchange is also described. This book is comprised of seven chapters and begins with a discussion on procedures for the separation of proteins, paying particular attention to the liberation of proteins from cellular material; removal of lipids from lipoproteins; and denaturation, fractionation, and purification of proteins. The next chapter focuses on the isolation of biologically active proteins such as cytochrome, bacterial amylases, and bacterial proteinases. The reader is methodically introduced to fractionation of proteins by adsorption and ion exchange; fractionation and characterization by dialysis; multi-membrane electrodecantation; and continuous and discontinuous partition. The final chapter explains how zonal density gradient electrophoresis works as a separation method for natural mixtures of proteins, their degradation products, and other substances carrying electric charges in solution or suspension. This volume will be of interest to chemists working with proteins.

Book Description
Proteins are an integral part of molecular and cellular structure and function and are probably the most purified type of biological molecule. In order to elucidate the structure and function of any protein it is first necessary to purify it. Protein purification techniques have evolved over the past ten years with improvements in equipment control, automation, and separation materials, and the introduction of new techniques such as affinity membranes and expanded beds. These developments have reduced the workload involved in protein purification, but there is still a need to consider how unit operations linked together to form a purification strategy, which can be scaled up if necessary. The two Practical Approach books on protein purification have therefore been thoroughly updated and rewritten where necessary. The core of both books is the provision of detailed practical guidelines aimed particularly at laboratory scale purification. Information on scale-up considerations is given where appropriate. The books are not comprehensive but do cover the major laboratory techniques and common sources of protein. Protein Purification Techniques focuses on unit operations and analytical techniques. It starts with an overview of purification strategy and then covers initial extraction and clarification techniques. The rest of the book concentrates on different purification methods with the emphasis being on chromatography. The final chapter considers general scale-up considerations. Protein Purification Applications describes purification strategies from common sources: mammalian cell culture, microbial cell culture, milk, animal tissue, and plant tissue. It also includes chapters on purification of inclusion bodies, fusion proteins, and purification for crystallography. A purification strategy that can produce a highly pure single protein from a crude mixture of proteins, carbohydrates, lipids, and cell debris to is a work of art to be admired. These books (available individually or as a set)are designed to give the laboratory worker the information needed to undertake the challenge of designing such a strategy.

Book Description
This open-end treatise on methods concerning pro tein separation had its beginning in an American Chemical Society symposium entitled "Con temporary Protein Separation Methods" which was held in Atlantic City, New Jersey in September 1974. The purpose of the symposium-and subse quently of the present work-was to review the available modern techniques and underlying principles för achieving one of the very important tasks of experimental biology, namely the separation and characterization of proteins present in complex biological mixtures. Physicochemical characterization was covered only as related to the parent method of fractionation and there fore involved mostly mass transport processes. Additionally, the presentation of methods for gaining insight into complex interacting protein profiles was considered of paramount importance in the interpretation of separation patterns. Finally, specific categories of proteins (e. g. , chemically modified, deriving from a specific tissue, conjugated to different moieties, etc. ) require meticulous trial and selection and/or modification of existing methodology to carry out the desired separation. In such cases, the gained experience provides valuable guidelines for further experimentation. Although powerful techniques exist today for the separation and related physicochemical characterization of pro teins, many biological fractionation problems require further innovations. It is hoped that the description in the present treatise of some of the available separation tools and their limitations will provide the necessary integrated background for new developments in this area.

Book Description
Success in meeting the challenge to produce the commercial products anticipated by the exploitation of biological processes depends upon provid ing effective separation protocols. Effectiveness can be measured in terms of selectivity, purity, resolution and validatory success. The major processing problems are associated with either the selective recovery of molecules which are present in low concentrations from complex mixtures or the selective removal of contaminants from the desired molecule. Central to the evolution of processes satisfying this demand are the regulatory requirements being imposed by governments on the purity of a product, especially in the health care market. Synthetic organic chemists are increasingly finding it advantageous to conduct one or more steps using either enzymic biotransformations where molecules with a single and consistent stereochemistry or chirality are required. The underlying princi ples behind the methods, techniques and processes currently being used and developed commercially rely upon the biospecific nature and properties of the desired molecule. When these factors are married to the more traditional techniques of precipitation, chromatography, liquid-liquid extraction and membrane processes, powerful tools emerge, allowing highly selective separations to be designed. The logical extension of these combinations is to apply genetic engineering techniques to influence the separations at a more fundamental and structural level by modifying the target protein at source, during its synthesis, to facilitate its separation in a given, selective manner, leading to the distinct possibility of producing 'designer' separation programmes.
