Dye pairs for measuring energy transfer fluorescence resonance (FRET).

摘要

Method for determining the interaction between biomolecules labeled with a donor and an acceptor, respectively, based on the principle of energy transfer fluorescence resonance and measuring the resulting fluorescence, wherein the donor energy used with metal chelate complexes of metals of groups VII or VIII of the transition elements, which are combined with low molecular weight fluorophores, between 300 d and 3000 d, which act as energy acceptors ions.
