@from:Praise for the Series @qu:"The Methods in Enzymology series represents the gold-standard." @source:--NEUROSCIENCE @qu:"Incomparably useful." @source:--ANALYTICAL BIOCHEMISTRY @qu:"It is a true 'methods' series, including almost every detail from basic theory to sources of equipment and reagents, with timely documentation provided on each page." @source:--BIO/TECHNOLOGY @qu:"The series has been following the growing, changing and creation of new areas of science. It should be on the shelves of all libraries in the world as a whole collection." @source:--CHEMISTRY IN INDUSTRY @qu:"The appearance of another volume in that excellent series, Methods in Enzymology, is always a cause for appreciation for those who wish to successfully carry out a particular technique or prepare an enzyme or metabolic intermediate without the tiresome prospect of searching through unfamiliar literature and perhaps selecting an unproven method which is not easily reproduced." @source:--AMERICAN SOCIETY OF MICROBIOLOGY NEWS @qu:"If we had some way to find the work most often consulted in the laboratory, it could well be the multi-volume series Methods in Enzymology...a great work." @source:--ENZYMOLOGIA @qu:"A series that has established itself as a definitive reference for biochemists." @source:--JOURNAL OF CHROMATOGRAPHY
