A method of determining a ligand of interest in a ligand is described. The method, which makes it possible to detect and quantify a ligand in a liquid, makes use of a biotin-avidin system which can be used to carry out immunoassays in both heterogeneous and homogeneous format. The basic components used in the method are a biotin-labeled substance (which is biotin-lableled ligand or biotin-labeled specific binding partner), biotin-labeled fluorophore, a liquid to be analyzed for the ligand of interest, specific binding partner for the ligand of interest and avidin.
