Abstract
A quantitative determination of a substance is performed in a homogeneous system based on a change in enzyme activity; differences between the activity of a free enzyme and that of an enzyme bound by an aggregation or chemical bonding are observed. A peroxidase-labeled antibody and antigen system is one of of the typical example. Since the reaction is effected in a homogeneous system, the amount of antigen can be easily measured by the difference of enzyme activity.
