摘要： A method for measuring a substance to be measured by means of a fluorescence, which comprises carrying out a measurement in the presence of (1) a specific fluorescent probe emitting a fluorescence by a specific reaction with the substance to be measured and (2) a donor having a long life fluorescence by itself and being capable of combining with the specific fluorescent probe as an acceptor and of allowing the acceptor to undergo a fluorescence resonance energy transfer (provided that the donor forms no chemical bonding with the specific fluorescent probe), wherein a fluorescence emitted by the reaction of the acceptor with the substance to be measured is converted to a long life fluorescence of excitation type by the fluorescence resonance energy transfer induced in the acceptor.
