The invention relates to a process for reducing the fluorescence quenching caused by the measuring medium in a fluorescence assay, by introducing into said medium of rare earth metal cryptates which are not very sensitive to this fluorescence quenching, said rare earth metal cryptates comprising at least one pyridine radical which is substituted one or more times or unsubstituted.
The invention also relates to novel rare earth metal cryptates which are not very sensitive to the fluorescence quenching caused by the measuring medium.
