WebAug 1, 2024 · SUMMARY: An outline for preparing enzyme assays 1. Set the conditions for the assay - choose the assay buffer and approximate assay volume. 2. Select the substrate concentration to use in each assay. 3. Calculate the stock substrate concentration knowing the largest volume and the largest substrate concentration. 4. 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.
