Abstract

The present invention concerns new fluorescent dye systems especially for fluorescence resonance energy transfer determinations for example combined with the time-resolved measurement of the resulting fluorescence. The invention also concerns the use of these dyes to label biomolecules and for the homogeneous determination of interactions between biomolecules, for example for detecting an analyte.
