Enzyme assays are a set of experimental techniques used to measure the activity of enzymes in various biological samples. They involve measuring the rate of a specific biochemical reaction, which is catalyzed by the enzyme of interest. Enzyme assays require specialized skills, knowledge, and equipment, and are used in many fields, including biochemistry, molecular biology, and pharmacology. Accurate measurement of enzyme activity provides valuable information about the function of enzymes in biological systems and their potential as drug targets.
