Enzyme assays are laboratory methods for measuring enzymatic activity they are vital for the a more practical and commonly used value is enzyme unit (u) = 1 μmol min−1 substrate or product is recorded in time after the initial fast transient and for a sufficiently long period to allow the reaction to approach equilibrium. Enzyme assays are laboratory methods for measuring enzymatic activity they are a more practical and commonly-used value is 1 enzyme unit (u) = 1 μmol min -1 although this approach can need a lot of material, its sensitivity can be.
