WebValidating Identity, Mass Purity and Enzymatic Purity of Enzyme Preparations When developing enzyme assays for HTS, the integrity of the target enzyme is critical to the quality of the HTS and the actives, or “hits”, identified through the screens. The % purity is 100% × (specific activity of enzyme sample / specific activity of pure enzyme). The impure sample has lower specific activity because some of the mass is not actually enzyme. If the specific activity of 100% pure enzyme is known, then an impure sample will have a lower specific activity, allowing purity … See more Enzyme assays are laboratory methods for measuring enzymatic activity. They are vital for the study of enzyme kinetics and enzyme inhibition. See more All enzyme assays measure either the consumption of substrate or production of product over time. A large number of different methods of measuring the concentrations of … See more Discontinuous assays are when samples are taken from an enzyme reaction at intervals and the amount of product production or … See more • MTT assay • Fluorescein diacetate hydrolysis • para-Nitrophenylphosphate See more The quantity or concentration of an enzyme can be expressed in molar amounts, as with any other chemical, or in terms of activity in enzyme units. Enzyme activity See more Continuous assays are most convenient, with one assay giving the rate of reaction with no further work necessary. There are many different types of continuous assays.
