Molecular Interactions in Bioseparations


Book Description

Rapid advances in molecular biology have accelerated the production of a great number of protein-based therapeutic agents. The major cost in producing these proteins appears to be associated with their purification from the complex mixture of the crude extract. A major challenge to the protein biochemist and the biochemical engineer is the development of rapid, efficient, and cost-effective purification systems. This volume presents state-of-the-art reviews of current methods used in the purifica tion of biological macromolecules that are based on molecular interactions. Thus, the major emphasis is placed on affinity-related techniques. Part I provides a general introduction to affinity chromatography and includes a chapter describing an interesting new technique called "slalom chromatography" for DNA fractionations. Affinity chromatography using molecules of biological origin as the affinity ligand is covered in Part II. Part III describes the use of a special class of biomolecules, antibodies, as affinity ligands. Affinity chromatography with biomimetic ligands is discussed in Part IV. Newer concepts and their applications in bioseparation are presented in Part V. Part VI covers affinity-related techniques such as affinity-based extracorporeal shunts, affinity electrophoresis, affinity precipitation, and affinity extraction. I would like to express my sincere thanks to all the authors, who are recognized experts in their respective fields, for their cooperation and contributions. I thank the editorial staff of Plenum Press for their professionalism, and Mary Phillips Born, Senior Editor, for her encouragement. The support of my family (Ping and Peilin) made it possible to complete editing this book. That T.




Handbook of Bioseparations


Book Description

It is generally recognized that the commercial success of biotechnology products is highly dependent on the successful development and application of high-powered separation and purification methods. In this practical and authoritative handbook, the separation of proteins, nucleic acids, and oligonucleotides from biological matrices is covered from analytical to process scales. Also included in a chapter on the separation of monoclonal antibodies, which have found numerous uses as therapeutic and diagnostic agents. Analytical techniques include an interesting montage of chromatographic methods, capillary electrophoresis, isoelectric focusing, and mass spectrometry. Among separation and purification methods, liquid-liquid distribution, displacement chromatography, expanded bed adsorption, membrane chromatography, and simulated moving bed chromatography are covered at length. Regulatory and economic considerations are addressed, as are plant and process equipment and engineering process control. A chapter on future developments highlights the application of DNA chip arrays as well as evolving methodologies for a large number of drugs that are under development for treatment of cancer, AIDS, rheumatoid arthritis, and Alzheimer's disease. Handbook of Bioseparations serves as an essential reference and guidebook for separation scientists working in the pharmaceutical and biotechnology industries, academia, and government laboratories.Key Features* Covers bioseparations of proteins, nucleic acids, and monoclonal antibodies* Encompasses both analytical and process-scale methods* Elucidates the importance of engineering process control* Details selection of plant and process equipment* Addresses economic considerations* Discusses future developments




Bioseparations of Proteins


Book Description

This book covers the fundamentals of protein inactivation during bioseparation and the effect on protein processing. Bioseparation of Proteins is unique because it provides a background of the bioseparation processes, and it is the first book available to emphasize the influence of the different bioseparation processes on protein inactivation.Bioseparation of Proteins covers the extent, mechanisms of, and control of protein inactivation during these processes along with the subsequent and essential validation of these processes. The book focuses on the avoidance of protein (biologicalproduct) inactivation at each step in a bioprocess. It compares protein inactivation exhibited during the different bioseparation processes by different workers and provides a valuable framework for workers in different areas interested in bioseparations.Topics include separation and detection methods; estimates of protein inactivation and an analysis of this problem for different separation processes; strategies for avoiding inactivation; the molecular basis of surface activity and protein adsorption,process monitoring, and product validation techniques; and the economics of various bioseparation processes and quality control procedures.Key Features* Protein inactivation and other aspects of biological stability are critical to an effective bioseparation process; This book is a detailed and critical review of the available literature in an area that is essential to the effectiveness, validation, and economics of bioseparation processes for drugs and other biological products; Conveniently assembled under one cover, the survey of the literature and resulting perspective will greatly assist engineers and chemists in designingand improving their own processes; Key features of the text include:* detailed data on biological stability under various bioseparation conditions* extensive case studies from the literature on separation processes, validation, and economics* simplified analysis of protein refolding and inactivation mechanisms* consideration of adsorption theories and the effect of heterogeneity* coverage of both classical and novel bioseparation techniques, including chromatographic procedures

Bioseparations Science and Engineering


Book Description

Designed for undergraduates, graduate students, and industry practitioners, Bioseparations Science and Engineering fills a critical need in the field of bioseparations. Current, comprehensive, and concise, it covers bioseparations unit operations in unprecedented depth. In each of the chapters, the authors use a consistent method of explaining unit operations, starting with a qualitative description noting the significance and general application of the unit operation. They then illustrate the scientific application of the operation, develop the required mathematical theory, and finally, describe the applications of the theory in engineering practice, with an emphasis on design and scaleup. Unique to this text is a chapter dedicated to bioseparations process design and economics, in which a process simular, SuperPro Designer® is used to analyze and evaluate the production of three important biological products. New to this second edition are updated discussions of moment analysis, computer simulation, membrane chromatography, and evaporation, among others, as well as revised problem sets. Unique features include basic information about bioproducts and engineering analysis and a chapter with bioseparations laboratory exercises. Bioseparations Science and Engineering is ideal for students and professionals working in or studying bioseparations, and is the premier text in the field.
