Electrophoretic methods play a crucial role in biochemical analysis and in many diverse fields, food science and genetic engineering among them. This new, extensively revised and up-dated edition covers all types of electrophoresis and focuses on recent techniques and developments. The book emphasizes forms of gel electrophoresis, specifically those methods based on polyacrylamide gels. The author has added two new chapters, on isotachophoresis and on two-dimensional electrophoresis, and has expanded the material on blotting techniques, isoelectric focusing in beds of granulated gel, and gel electrophoresis in organic solvents. From reviews of the first edition: "Dr. Andrews is to be congratulated on providing under one cover, succinct, clear, and practical descriptions of electrophoresis." --Nature. "A must for biologists, immunologists, microbiologists, and any scientist interested in modern separation science." --Journal of the American Chemical Society
