Isolation And Purification Of Proteins

This publication details the isolation of proteins from biological materials, techniques for solid-liquid separation, concentration, crystallization, chromatography, scale-up, process monitoring, product formulation, and regulatory and commercial considerations in protein production. The authors discuss the release of protein from a biological host, selectivity in affinity chromatography, precipitation of proteins (both non-specific and specific), extraction for rapid protein isolation, adsorption as an initial step for the capture of proteins, scale-up and commercial production of recombinant proteins, and process monitoring in downstream processing.

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.

It is a truism of science that the more fundamental the subject, the more universally applicable it is. Neverthelens, it is important to strike a level of "fundamentalness" appropriate to the task in hand. For example, an in-depth study of the mechanics of motor cars would tell one nothing about the dynamics of traffic. Traffic exists on a different "level" - it is dependent upon the existence of motor vehicles but the physics and mathematics of traffic can be adequately addressed by considering motor vehicles as mobile "blobs", with no consideration of how they become mobile. To start a discourse on traffic with a consideration of the mechanics of motor vehicles would thus be inappropropriate. In writing this volume, I have wrestled with the question of the appropriate level at which to address the physics underlying many of the techniques used in protein isolation. I have tried to strike a level as would be used by a mechanic (with perhaps a slight leaning towards an engineer) - i.e. a practical level, offering appropriate insight but with minimal mathematics. Some people involved in biochemical research have a minimal grounding in chemistry and physics and so I have tried to keep it as simple as possible.

Guide to Protein Purification, Second Edition provides a complete update to existing methods in the field, reflecting the enormous advances made in the last two decades. In particular, proteomics, mass spectrometry, and DNA technology have revolutionized the field since the first edition’s publication but through all of the advancements, the purification of proteins is still an indispensable first step in understanding their function. This volume examines the most reliable, robust methods for researchers in biochemistry, molecular and cell biology, genetics, pharmacology and biotechnology and sets a standard for best practices in the field. It relates how these traditional and new cutting-edge methods connect to the explosive advancements in the field. This "Guide to" gives imminently practical advice to avoid costly mistakes in choosing a method and brings in perspective from the premier researchers while presents a comprehensive overview of the field today. Gathers top global authors from industry, medicine, and research fields across a wide variety of disciplines, including biochemistry, genetics, oncology, pharmacology, dermatology and immunology Assembles chapters on both common and less common relevant techniques Provides robust methods as well as an analysis of the advancements in the field that, for an individual investigator, can be a demanding and time-consuming process

Proteins are important biomolecules that are vital for the cellular structure and function. They perform a vast array of functions within organisms, including the catalysis of metabolic reactions, DNA replication, response to stimuli, and transporting molecules from one location to another. The technological advances in the omics areas (e.g., genomics, transcriptomics, proteomics, metagenomics, etc.) have dramatically increased the rate of discovering new proteins. Some of them hold large opportunities for innovative research and the development of commercial products and applications. It is worth noting that the global protein ingredients market is poised to grow over the next decade to reach approximately 58.49 billion USD by 2022, with the protein therapeutics market valuing around USD 315.9 billion by 2025. Interestingly, about seventy monoclonal antibody products will be on the market by 2020 with a combined worldwide sales of about 125 billion USD.The most significant parameter for the successful commercial exploitation of proteins rely on the development of an efficient and effective isolation and purification technology, known as protein downstream processing. Downstream processing refers to the technology that involves the isolation and production of purified products from natural sources such as animal tissues, plant tissues, microorganisms or fermentation broth. The most important element of this technology is the high purification processes, most important of which is chromatography and in particular affinity chromatography.This book provides information on the resent developments of protein downstream processing and deals with the information gained over the last years from the application of protein purification technologies on different research areas. Each chapter gives key examples that cover a wide range of diverse scientific disciplines in order to provide the reader with a representative sample of the current status of the field. The present book would definitely be an ideal source of scientific information to the advanced students, junior researchers, and scientists involved in cellular and molecular biology, biochemistry, microbiology, biotechnology and other related areas.

A textbook for an undergraduate or professional training course for students with a solid background in general biology and chemistry, and hopefully some organic chemistry; does not assume any microbiology and biochemistry. Explains the laboratory techniques and skills for characterizing and purifying a protein and for cloning the associated gene, and the strategies and rationale for the research process itself. The examples use readily available materials and organisms to keep the cost down. Annotation copyright by Book News, Inc., Portland, OR
