Immobilized Biochemicals And Affinity Chromatography

This volume contains most of the papers presented at the Sym posium on Affinity Chromatography and Immobilized Biochemicals, which was held on November 7-9, 1973 in Charleston, South Carolina in conjunction with the Southeastern Regional American Chemical Society meeting. The topics of the symposium represent two new biochemical frontiers which have emerged in recent years through the ingenious development and application of solid phase biochemi cal technologies. Affinity chromatography involves the use of selected ligands, covalently bound to a solid support such as cel lulose, glass, Sepharose, or polyacrylamide and exploits the princi ple of biochemical recognition between the ligand in the solid phase and a selected macromolecule to facilitate the rapid and often quantitative purification of enzymes, antibodies, antigens, hormones, other proteins, etc. The area of immobilized biochemicals includes the use of coenzymes, oligo- and po1ynuc1eotides, enzymes, and multistep enzyme systems which are immobilized or entrapped in the solid phase. The goals of the symposium were the revi~w of the status of affinity chromatography and immobilized biochemicals, the presentation of new data and ideas in both areas, and the establish ment of a dialogue between research workers in these two evolving disciplines which are so closely interrelated. The papers published in this volume provide the reader with reviews of several topics inherent in the solid phase biochemistry together with a series of timely manuscripts concerning new techniques and applications both in the use of affinity chromatography and in the investigation of immobilized biochemicals.

This book is a practical guide to the preparation and use of immobilized affinity ligands for purification, catalysis, and analysis. Special emphasis is given to immunochemical techniques including antibody isolation, preparation of antibody fragments using immobilized enzymes, and immunoaffinity chromatography. The book provides easy-to-follow, well-tested protocols to allow the uninitiated to use these techniques to the maximum advantage with minimum hassle. In addition, it shows researchers how to save money by making their own optimized affinity supports.

Affinity chromatography, with its exquisite specificity, is based upon molecular recognition. It is a powerful tool for the purification of biomolecules. In recent years, numerous new applications and modified techniques have been derived from gro- specific interactions and biological recognition principles. An up-to-date review of the past, current, and future applications of affinity chromatography has been presented in the introductory chapter by Meir Wilchek and Irwin Chaiken. Though many of these new applications and techniques are well documented in the literature, it is often difficult to find methods that are written with the intent of helping new practitioners of affinity chromatography. This volume on Affinity Chromatography: Methods and Protocols is intended for the novice, as well as for - perts in the field. The protocols are written by experts who have developed and/or successfully employed these methods in their laboratories. Each chapter describes a specific technique, and since the book is intended to help the beginner, each technique is described simply and clearly, making sure that all relevant steps are included, assuming no previous knowledge. Each chapter contains an introduction describing the principles involved, followed by a Materials and Methods section, which lays the groundwork for the reader to conduct experiments step-by-step, in an orderly fashion. The following Notes section, which describes many of the problems that can occur, makes suggestions for overcoming them, and provides alternate procedures. These are precisely the sort of important, practical details that never seem to appear in the published literature.

The Handbook of Affinity Chromatograph

The authoritative guide on protein purification—now completely updated and revised Since the Second Edition of Protein Purification was published in 1998, the sequencing of the human genome and other developments in bioscience have dramatically changed the landscape of protein research. This new edition addresses these developments, featuring a wealth of new topics and several chapters rewritten from scratch. Leading experts in the field cover all major biochemical separation methods for proteins in use today, providing professionals in biochemistry, organic chemistry, and analytical chemistry with quick access to the latest techniques. Entirely new or thoroughly revised content includes: High-resolution reversed-phase liquid chromatography Electrophoresis in gels Conventional isoelectric focusing in gel slabs and capillaries and immobilized pH gradients Affinity ligands from chemical and biological combinatorial libraries Membrane separations Refolding of inclusion body proteins from E. coli Purification of PEGylated proteins High throughput screening techniques in protein purification The history of protein chromatography

One major concern of biotechnology is either using enzymes or producing them. Enzyme/protein production is therefore an important starting point for biotechnology. Bioseparation or Downstream Processing constitutes about 40-90% of the total production cost. Driven by economics, highly selective technologies applicable to large-scale processing have emerged during the last decade. These technologies are slowly diffusing to enzymologists who are working on a smaller scale, looking for fast and efficient purification protocols. The affinity-based techniques (including precipitation, two-phase extractions, expanded bed chromatography, perfusion chromatography and monoliths) described in this volume provide current and new cutting-edge methods. Consequently, the book is of main interest to researchers in biochemistry, biochemical engineering and biotechnology, working either in academic or industrial sectors.
