Isolation and Purification of Proteins


Book Description

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.




A Guide to Protein Isolation


Book Description

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.

Protein Purification Protocols


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.

Handbook on Protein Purification


Book Description

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.

Protein Chromatography


Book Description

A prerequisite for elucidating the structure and function of any protein is the prior purification of that protein. This necessity has led to the development of many purification schemes and chromatographic methods for the isolation of native proteins from complex sources. In Protein Chromatography: Methods and Protocols, leading researchers present clear protocol-style chapters that are suitable for newcomers and experts alike. The book opens with vital topics in protein biochemistry, addressing such areas as protein stability and storage, avoiding proteolysis during chromatography, protein quantitation methods including immuno-qPCR, and the contrasting challenges that microfluidics and scale-up production pose to the investigator, and then it segues into key methods involving the generation and purification of recombinant proteins through recombinant antibody production and the tagging of proteins, amongst other means, as well as many variations on classic techniques such as ion-exchange and immunoaffinity chromatography. Written in the highly successful Methods in Molecular BiologyTM series format, protocols chapters include introductions to their respective subjects, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Protein Chromatography: Methods and Protocols will greatly aid scientists in establishing these essential techniques in their own laboratories and furthering our understanding of the many imperative functions of proteins.
