This standard work in the field of protein purification covers a broad range of techniques, both in chromatography and electrophoresis. It provides a comprehensive background for anyone seriously moving into the area. Since the Second Edition of Protein Purification was published in 1998, the sequencing of the human genome and other developments in biosciences has dramatically changed the landscape of protein research. This new edition addresses these developments, featuring a wealth of new topics and several chapters that have been completely rewritten.
