The Separation And Isolation Of Proteins

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.

A Laboratory Manual of Analytical Methods of Protein Chemistry (Including Polypeptides), Volume 1: The Separation and Isolation of Proteins deals with the techniques used in the separation and isolation of proteins, including fractionation and characterization by dialysis, multi-membrane electrodecantation, and zonal density gradient electrophoresis. The fractionation of proteins by adsorption and ion exchange is also described. This book is comprised of seven chapters and begins with a discussion on procedures for the separation of proteins, paying particular attention to the liberation of proteins from cellular material; removal of lipids from lipoproteins; and denaturation, fractionation, and purification of proteins. The next chapter focuses on the isolation of biologically active proteins such as cytochrome, bacterial amylases, and bacterial proteinases. The reader is methodically introduced to fractionation of proteins by adsorption and ion exchange; fractionation and characterization by dialysis; multi-membrane electrodecantation; and continuous and discontinuous partition. The final chapter explains how zonal density gradient electrophoresis works as a separation method for natural mixtures of proteins, their degradation products, and other substances carrying electric charges in solution or suspension. This volume will be of interest to chemists working with proteins.

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.

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.

New textbooks at alllevels of chemistry appear with great regularity. Some fields like basic biochemistry, organic reaction 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 reallack ofup-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 which is advancing the field. lt is not often easy to persuade such individuals to settime aside to help spread the knowledge they have accumu lated. 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 instructive introductions to their fields. These should serve the needs of one semester or one quarter graduate courses in chemistry and biochemistry. In some cases the availability of texts in active research areas should help stimulate the creation of new courses. NewYork CHARLES R.
