Downstream Processing Of Proteins

Considerable effort and time is allocated to introducing cell culture and fermentation technology to undergraduate students in academia, generally through a range of courses in industrial biotechnology and related disciplines. Similarly, a large number of textbooks are available to describe the appli- tions of these technologies in industry. However, there has been a general lack of appreciation of the significant developments in downstream processing and isolation technology, the need for which is largely driven by the stringent re- latory requirements for purity and quality of injectable biopharmaceuticals. This is particularly reflected by the general absence of coverage of this s- ject in many biotechnology and related courses in educational institutions. For a considerable while I have felt that there is increasing need for an introductory text to various aspects of downstream processing, particularly with respect to the needs of the biopharmaceutical and biotechnology ind- try. Although there are numerous texts that cover various aspects of protein purification techniques in isolation, there is a need for a work that covers the broad range of isolation technology in an industrial setting. It is anticipated that Downstream Processing of Proteins: Methods and Protocols will play a small part in filling this gap and thus prove a useful contribution to the field. It is also designed to encourage educational strategists to broaden the coverage of these topics in industrial biotechnology courses by including accounts of this important and rapidly developing element of the industrial process.

Proteins are the most diverse group of biologically important substances. With the recent technological advances in the genomics area and the efforts in proteomics research, the rate of discovery for new proteins with unknown structure and function has increased. These proteins generated from genomic approaches present enormous opportunities for research and industrial application. Protein Downstream Processing: Design, Development and Application of High and Low-Resolution Methods is a compilation of chapters within the exciting area of protein purification designed to give the laboratory worker the information needed to design and implement a successful purification strategy. It presents reliable and robust protocols in a concise form, emphasizing the critical aspects on practical problems and questions encountered at the lab bench. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Protein Downstream Processing: Design, Development and Application of High and Low-Resolution Methods will be an ideal source of scientific information to advanced students, junior researchers, and scientists involved in health sciences, cellular and molecular biology, biochemistry, and biotechnology and other related areas in both academia and industry. ​

This second edition volume expands on the previous edition with updated research and techniques to help laboratory workers design and implement a successful purification strategy, emphasize critical aspects on practical problems, and answers questions encountered at the lab bench. The chapters in this book are divided into five parts: Part One discusses an overview of screening and design of purification strategies and covers initial aspects on high-throughput screening, methods development, and media selection; Parts Two and Three explore low- and high-resolution methods, with emphasis on affinity chromatography; Part Four describes analytical techniques of purified proteins; and Part Five presents selected examples and case studies to discuss the aforementioned. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and comprehensive, Protein Downstream Processing: Design, Development, and Application of High and Low-Resolution Methods, Second Edition is an ideal source of information to advanced students, junior researchers, and scientists involved in health sciences, cellular and molecular biology, biochemistry, biotechnology, and other related areas in both academia and industry.

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.

Mohamed A. Desai and a team of experienced biotechnologists review both conventional and novel isolation techniques used in industrial applications for the downstream processing of protein molecules. These techniques include primary and secondary separations during the isolation of biomolecules, as well as unique laboratory-scale research methods from academia with a potential for scale-up. Also treated are various strands of the downstream biological process essential for a successful product license application, including both the validation of DSP stages, and the design and validation of viral clearance stages during the purification process. Downstream Processing of Proteins: Methods and Protocols provides scientists everywhere, but particularly in the biopharmaceutical and biotechnology industry, with a much-needed introduction to this critical technology.

A comprehensive introduction to the art and science used by the biochemist and process engineer in the design and optimization of large-scale protein-purification processes. Covers the basics of proteins' properties, the unit operations involved in protein purification as well as important related issues of process design, integration with upstream operations, cost and timing to market. Includes an abundance of figures and tables.
