COLORIMETRIC MEASUREMENT OF ENZYMATIC ACTIVITY IN CELL LYSATES

摘要

The present invention concerns a method for the calorimetric measurement of enzyme activity comprising the following steps: preparing a cell suspension or a cell lysate containing cell components, adding a chromogenic substrate at the start of the enzyme reaction, adding a first additional substance to stop the enzyme reaction, and making a colorimetric measurement, wherein a second additional substance which reduces the light scattering and/or absorption caused by the cells or the cell components is added during or after termination of the enzyme reaction.
