Abstract：
:Enzymes have proven to be sensitive and versatile labels for immunochemical assays. The sensitivity of an enzyme label stems from its extraordinary catalytic power which in turn provides a great amplification of signals. Its versatility, however, stems from the fact that enzyme activity can be modulated by a number of substances. Enzyme labeled immunoassays can be divided into two categories: (a) heterogeneous and (b) homogeneous (non-separation). In the heterogeneous systems, the quantitation of the antibody bound and unbound fractions requires a physical separation of these two fractions, whereas the homogeneous or non-separation systems do not require such a separation. In the homogeneous systems, the unbound and antibody bound fractions can be distinguished functionally. A total of 11 unique principles used in the development of enzyme labeled immunoassays are described. The advantages, disadvantages and limitations of them are considered, as well as the future paths for research and developments.
