Protein Purification Protocols


Book Description

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.




Protein Purification Protocols


Book Description

Hans Neurath has written that this is the second golden era of enzymology {Protein Science [1994], vol. 3, pp. 1734—1739); he could with justice have been more general and referred to the second golden age of protein chemistry. The last two decades have seen enormous advances in our understanding of the structures and functions of pro teins arising on the one hand from improvements and developments in analytical techniques {see the companion volume, Basic Protein and Peptide Protocols, in this series) and on the other hand from the tech nologies of molecular genetics. Far from turning the focus away from protein science, the ability to isolate, analyze, and express genes has increased interest in proteins as gene products. Hence, many laborato ries are now getting involved in protein isolation for the first time, either as an essential adjunct to their work in molecular genetics or because of a curiosity to know more about the products of the genes that they have been studying. Protein Purification Protocols is aimed mainly at these newcom ers to protein purification, but it is hoped that it will also be of value to established practitioners who may find here techniques that they have not tried, but which might well be most applicable in their work. With the exception mainly of the first and last chapters, the format of the contributions to the present book conform to the established format of the Methods in Molecular Biology series.




Membrane Protein Protocols


Book Description

Knowledge of the three-dimensional structure of a protein is absolutely required for the complete understanding of its function. The spatial orientation of amino acids in the active site of an enzyme demonstrates how substrate specificity is defined, and assists the medicinal chemist in the design of s- cific, tight-binding inhibitors. The shape and contour of a protein surface hints at its interaction with other proteins and with its environment. Structural ana- sis of multiprotein complexes helps to define the role and interaction of each individual component, and can predict the consequences of protein mutation or conditions that promote dissociation and rearrangement of the complex. Determining the three-dimensional structure of a protein requires milligram quantities of pure material. Such quantities are required to refine crystallization conditions for X-ray analysis, or to overcome the sensitivity limitations of NMR spectroscopy. Historically, structural determination of proteins was limited to those expressed naturally in large amounts, or derived from a tissue or cell source inexpensive enough to warrant the use of large quantities of cells. H- ever, with the advent of the techniques of modern gene expression, many p- teins that are constitutively expressed in minute amounts can become accessible to large-scale purification and structural analysis.




Protein Purification Protocols


Book Description

In this new edition of the very successful Protein Purification Protocols (1996), Paul Cutler completely updates the existing protocols to reflect recent advances and adds an enormous new array of proteomic techniques for protein isolation and analysis. These cutting-edge techniques include not only two-dimensional gel electrophoresis for analysis and characterization, but also analytical chromatography for multidimensional separations of proteins and peptides, and mass spectrometry for isolating proteins. With the many recent advances in technology, simple spectrometric detection is no longer the only option for separating proteins, and the authors treat in full detail all the newer methods for these separations. Comprehensive and highly practical, Protein Purification Protocols, Second Edition, brings together all the key methodologies that both novice and experienced investigators need to carry out successful experimental work on proteins and their functions today.

Protein Chromatography


Book Description

A prerequisite for elucidating the structure and function of any protein is the prior purification of that protein. This necessity has led to the development of many purification schemes and chromatographic methods for the isolation of native proteins from complex sources. In Protein Chromatography: Methods and Protocols, leading researchers present clear protocol-style chapters that are suitable for newcomers and experts alike. The book opens with vital topics in protein biochemistry, addressing such areas as protein stability and storage, avoiding proteolysis during chromatography, protein quantitation methods including immuno-qPCR, and the contrasting challenges that microfluidics and scale-up production pose to the investigator, and then it segues into key methods involving the generation and purification of recombinant proteins through recombinant antibody production and the tagging of proteins, amongst other means, as well as many variations on classic techniques such as ion-exchange and immunoaffinity chromatography. Written in the highly successful Methods in Molecular BiologyTM series format, protocols chapters include introductions to their respective subjects, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Protein Chromatography: Methods and Protocols will greatly aid scientists in establishing these essential techniques in their own laboratories and furthering our understanding of the many imperative functions of proteins.

Downstream Processing of Proteins


Book Description

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.




High Throughput Protein Expression and Purification


Book Description

Despite exciting advances in genome sequencing, isolating a protein from its expression system in its native form still presents a complex challenge. In High Throughput Protein Expression and Purification: Methods and Protocols, leading scientists detail the most successful protocols currently in use, including various high throughput cloning schemes, protein expression analysis, and production protocols. This volume describes the use of E. coli, insect, and mammalian cells, as well as cell-free systems for the production of a wide variety of proteins, including glycoproteins and membrane proteins, in order to best represent strategies that create and exploit common features to enable simplified cloning, stable expression, and purification of proteins. Written in the highly successful Methods in Molecular BiologyTM series format, the chapters present brief introductions to the subject, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and a Notes section for tips on troubleshooting and avoiding known pitfalls. Cutting-edge and comprehensive, High Throughput Protein Expression and Purification: Methods and Protocols is an ideal reference for protein biochemists and all those who wish to apply these easy-to-use protocols to the many applicable fields.




HPLC of Peptides and Proteins


Book Description

The introduction of high-performance liquid chromatography (HPLC) to the analysis of peptides and proteins some 25 years ago revolutionized the biological sciences by enabling the rapid and sensitive analysis of peptide and protein structure through the exquisite speed, sensitivity, and resolution that can be easily obtained. Today, HPLC in its various modes has become the pivotal technique in the characterization of peptides and proteins and currently plays a critical role in both our understanding of biological processes and in the development of peptide- and protein-based pharmaceuticals. The number of applications of HPLC in peptide and protein purification continues to expand at an extremely rapid rate. Solid-phase peptide synthesis and recombinant DNA techniques have allowed the production of large quantities of peptides and proteins that need to be highly purified. HPLC techniques are also used extensively in the isolation and characterization of novel proteins that will become increasingly important in the postgenomic age. The design of multidimensional purification schemes to achieve high levels of product purity further demonstrates the power of HPLC techniques not only in the characterization of cellular events, but also in the production of pepti- and protein-based therapeutics. HPLC continues to be at the heart of the analytical techniques with which scientists in both academia and in industry must arm themselves to be able to fully characterize the identity, purity, and potency of peptides and proteins.
