  • Method for measurement by using long-lived excitation fluorescence
    Publication number: 20060252099
    Abstract: A method for measurement of a target substance in a sample by means of fluorescence, which comprises the step of carrying out the measurement in the presence of (1) a specific fluorescent probe which specifically reacts with the target substance to generate fluorescence, and (2) a donor which, per se, has long-lived fluorescence and is capable of inducing fluorescence resonance energy transfer to the specific fluorescent probe that acts as an acceptor, provided that the donor forms no binding to the specific fluorescent probe by means of a chemical bond; and the step of converting fluorescence, wherein said fluorescence is resulted from a reaction between the acceptor and the target substance, into long-lived excitation fluorescence by the fluorescence resonance energy transfer which is induced on the acceptor.
