Abstract
The invention relates to a method and novel reagents for detecting a ligand in a biological sample. In the method, the sample is combined with (i) an enzyme or an enzyme bound to a first macromolecular compound, (ii) substrate for the enzyme, and (iii) an antibody complex comprising anti-ligand bound to anti-enzyme and a second macromolecular compound bound to either one or both of the anti-ligand and anti-enzyme. The activity of the enzyme varies as a function of the unknown amount of ligand contained in the biological sample.
