This twelve volume series is a useful reference manual for work in the laboratory. Seven hundred authors from 29 countries describe the methods of enzymatic analysis in a way that corresponds to the various steps undertaken in laboratory routine. Designed for use in the laboratory rather than in the library, the third edition takes into account recent changes in symbolism, nomenclature, & enzyme classification. The series provides information on the precision of measurement, the sensitivity & limitation of a method, & on possible alternatives. Annotations by the authors convey their personal experience by including useful hints, remarks & experimental tricks to make the method truly workable.
