Abstract
A bioassay employing a first group including a lanthanide ion carrier chelate and a first recognition element, a second group including an antenna ligand and a second recognition element; where the lanthanide ion carrier chelate binds strongly to lanthanide, or the lanthanide ion carrier chelate binds moderately to lanthanide, and an agent complexing the lanthanide ion is additionally employed at a concentration of at least 1 pmol/l. The antenna ligand binds weakly to the lanthanide ion. Analyte recognition by the first recognition element and by the second recognition element results in either chelate complementation and increased fluorescence, or chelate discomplementation and decreased fluorescence.
