How to measure enzymatic activity
WebEnzyme unit. The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme 's catalytic activity. [1] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method. [2] WebActivity 1: Measuring the Enzymatic Activity of Lactase How would we measure the activity of a specific enzyme? One easy way to measure the concentration of a chemical is by using a colored indicator. As an enzymatic reaction proceeds, the color of the solution changes, and can be monitored visually.

In each well 190 μL phosphate buffer (50 mM, pH 7.4) and 10 μL enzyme preparation is pipetted. 40 μL of substrate (solved in DMSO) at different concentrations is added using the onboard injectors. The final volume per well is 240 μL.
Web1. Cut thin sections of fast-growing roots or germinating seeds or take some pollen grains and put the material in phosphate buffer at pH 7.0. Now transfer the material in the incubation mixture [made of 5% benzidine saturated solution + 5 ml hydrogen peroxide (1%) and 1 ml ammonium chloride (5%)].
