Book excerpt: This book presents a selection of tried and trusted laboratory experiments in the field of biochemistry. The experiments are described in detail and can be used directly or in a modified form. They are grouped according to a broad range of biochemical disciplines which allows those responsible for arranging practical classes to select experiments to complement any given biochemistry course. Suggestions are made for further work in more advanced classes. As well as the practical method the experiments are accompanied by background information, discussion of results, references for further study and illustrations.
