This invention provides a combinatorial fluorescence energy transfer tag whi ch comprises a plurality of fluorescent molecules, comprising one or more energ y transfer donor and one or more energy transfer acceptor, linked through a molecular scaffold wherein the fluorescent molecules are separated along the scaffold to produce a unique fluorescene emission signature. The invention further provides for the use of said tags in multi-component analyses, including multiplex biological analyses.
