摘要:
A novel nucleic acid probe for nucleic acid determination includes a single-stranded nucleic acid labeled with plural fluorescent dyes containing at least one pair of fluorescent dyes to induce FRET, the pair of fluorescent dyes including a fluorescent dye (a donor dye) capable of serving as a donor dye and a fluorescent dye (an acceptor dye) capable of serving as an acceptor dye, in which the nucleic acid probe has such a base sequence and is labeled with the fluorescent dyes so that the fluorescence intensity of the acceptor dye decreases upon hybridization with a target nucleic acid. A novel nucleic acid determination method uses the probe. The probe and method can determine one or more types of target nucleic acids in an assay system in parallel using a simple apparatus.

摘要:
Nucleic acid probes are provided, each of which is formed of a single-stranded oligonucleotide which can hybridize to a target nucleic acid and is labeled with a fluorescent dye or with a fluorescent dye and a quencher substance. The nucleic acid probes can be easily designed, permit determination, polymorphous analysis or real-time quantitative PCR of nucleic acids in short time, and are not dissociated during reactions. Nucleic acid determination methods, polymorphous analysis methods and real-time quantitative PCR methods, which make use of the nucleic acid probes, are also provided.
摘要:
A method is provided for determining a concentration of a target nucleic acid by using a nucleic acid probe labeled with a fluorescent dye. The method comprises: providing, as the probe, a nucleic acid probe capable of reducing fluorescence emission from the fluorescent dye when hybridized with the target nucleic acid; hybridizing the probe to the target nucleic acid; and measuring a decrease in fluorescence emission from the fluorescent dye after the hybridization relative to fluorescence emission from the fluorescent dye before the hybridization.
