The present invention provides a fluorescence assay by introducing a rare earth metal cryptate measurement medium, which is less sensitive to fluorescence quenching, containing at least one pyridine group, which is substituted or unsubstituted one or more times. A method for reducing fluorescence quenching caused by a measurement medium. The invention also relates to novel rare earth metal cryptates which are less sensitive to fluorescence quenching caused by the measurement medium.

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.
