Methods For Affinity Based Separations Of Enzymes And Proteins

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.

This is a state-of-the-art sourcebook on modern high-resolution biochemical separation techniques for proteins. It contains all the basic theory and principles used in protein chromatography and electrophoresis.

Thirty-eight years after its introduction, affinity chromatography remains a key tool in the armory of separation techniques available to separation and interaction scientists. Expanded and updated from the first edition, Affinity Chromatography: Methods and Protocols, Second Edition, provides the beginner with the practical knowledge needed to develop affinity separations suitable for a variety of applications relevant to the post-genomic era. This second edition expands on the first edition by introducing more state-of-the-art protocols used in affinity chromatography. This new edition also describes protocols that demonstrate the concept of affinity chromatography being applied to meet the modern high throughput screening demands of researchers and development scientists whilst expanding on some more traditional affinity chromatography approaches that have become of greater interest to separation scientists. Chapters in this cutting-edge text expand on affinity chromatography techniques that currently enjoy frequent citation in the literature from those purifying biomolecules. Other chapters include protocols describing the use of a variety of fusion tags as well as how to cleave them, so as to allow the scientists to study the native phenotype of the protein. Renowned researchers also include protocols detailing diverse applications of affinity chromatography such as its use in catalytic reactions, DNA purification, whole cell separations and for the isolation of phosphorylated proteins. Affinity Chromatography: Methods and Protocols, Second Edition, is an essential reference for those interested in separation sciences, particularly in the pharmaceutical and biological research sectors, that have an interest in isolating macromolecules rapidly, quantitatively, and with high purity.

New textbooks at all levels of chemistry appear with great regularity. Some fields such as basic biochemistry, organic re action mechanisms, and chemical thermodynamics are weil represented by many excellent texts, and new or revised editions are published sufficiently often to keep up with progress in research. However, some areas of chemistry, especially many of those taught at the graduate level, suffer from a real lack of up-to-date textbooks. The most serious needs occur in fields that are rapidly changing. Textbooks in these subjects usually have to be written by scientists actually involved in the research that is advancing the field. It is not often easy to persuade such individuals to set time aside to help spread the knowledge they have accumulated. Our goal, in this series, is to pinpoint areas of chemistry where recent progress has outpaced what is covered in any available textbooks, and then seek out and persuade experts in these fields to produce relatively concise but instruc tive introductions to their fields. These should serve the needs of one semester or one quarter graduate courses in chemistry and biochemistry. In so me cases the availability of texts in active research areas should help stimulate the creation of new courses.

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.

The first edition of Protein Purification Protocols (1996), edited by Professor Shawn Doonan, rapidly became very successful. Professor Doonan achieved his aims of p- ducing a list of protocols that were invaluable to newcomers in protein purification and of significant benefit to established practitioners. Each chapter was written by an ex- rienced expert in the field. In the intervening time, a number of advances have w- ranted a second edition. However, in attempting to encompass the recent developments in several areas, the intention has been to expand on the original format, retaining the concepts that made the initial edition so successful. This is reflected in the structure of this second edition. I am indebted to Professor Doonan for his involvement in this new edition and the continuity that this brings. Each chapter that appeared in the original volume has been reviewed and updated to reflect advances and bring the topic into the 21st century. In many cases, this reflects new applications or new matrices available from vendors. Many of these have increased the performance and/or scope of the given method. Several new chapters have been introduced, including chapters on all the currently used protein fractionation and ch- matographic techniques. They introduce the theory and background for each method, providing lists of the equipment and reagents required for their successful execution, as well as a detailed description of how each is performed.
