VERFAHREN ZUR BESTIMMUNG VON TERBIUM ODER EUROPIUM ENTHALTENDEN CHEMISCHEN KOMPONENTEN

摘要

A method whereby the presence and/or amount of a chemical moiety containing lanthanide, e.g. terbium or europium is determined by applying an electrical pulse into an electrode immersed in a solution and measuring the delayed light emission after some time from the end of the pulse, said chemical moiety being either bound to said electrode and/or present in said solution and said emitted light being taken as an indication of the amount of the chemical moiety present in the proximity of said electrode. The method is useful especially for analytical methods based on binding assays such as immunoassays and nucleic acid hybridization assays.
