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

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.

Book Description
Ultrafiltration (UF) is a pressure-driven separation process in which membranes are used for a broad variety of applications, ranging from the processing of biological macromolecules to wastewater treatment. It has significant advantages over competing separation technologies. Food and biotechnological applications of UF account for nearly 40 percent of the current total usage. In the case of high value therapeutic protein and DNA products, the separation and purification costs can be as high as 80 percent of the total cost of production. Therefore, it makes economic sense to develop cost-effective and scaleable purification processes for such products. UF is used for protein concentration, protein desalting and protein fractionation (such as protein-protein separation). Concentration and desalting processes are technologically less demanding and have been widely used in the bioprocess industry for quite some time. Protein fractionation, on the other hand, is a challenging proposition and is definitely a more recent development. This text focuses primarily on protein fractionation.

Book Description
The use of biotechnology in chemical synthesis offers up numerous advantages to the engineer in the process industries, but it also presents a number of fundamental challenges and difficulties which impinge directly on separation process requirements. The use of biochemical separations has grown significantly during the past decade, and is especially used in process industries such as healthcare and food processing. However it is becoming increasingly more important in areas such as recycling and waste-water treatment and as industry shifts towards cleaner processes biochemical separations will continue to grow. The two main objectives of this book are to focus on the application of existing separation process techniques to the recovery and purification of biologically derived products and to examine the state of knowledge of new techniques which have future potential. Within these objectives the complexities and breadth of problems associated with biological separations are discussed, specific engineering techniques are featured and their adaptation to biochemical separations are highlighted.
