The purpose of the present invention is to provide: a novel method for detecting a target nucleic acid; and a kit for use in the method. In the detection method according to the present invention, a fluorophore-labeled primer/probe and a quencher-labeled probe, which have complementarity to each other, are so designed as to have different melting temperatures (Tm) from each other so that the fluorophore-labeled primer can anneal preferentially to the target nucleic acid. The detection method is so designed that the fluorophore-labeled primer/probe that is not bound to the target nucleic acid is bound to the quenching probe so as to emit no fluorescence. The method enables the detection of the target nucleic acid in a simpler manner, at lower cost, and without requiring the use of any technique or device.

Method for detecting target nucleic acid

The object of the present invention is to provide a method that allows stable amplification of an internal standard material while maintaining an accurate assay value for a target nucleic acid in a nucleic acid detection system involving the use of an internal standard material and a reagent kit used therefor. The present invention relates to a method for nucleic acid amplification comprising preventing an internal standard amplification product from affecting amplification reaction of a target nucleic acid by performing amplification of an internal standard material prior to amplification of the target nucleic acid in the method for amplifying a target nucleic acid in a sample using an internal standard material and a reagent and reagent kit used therefor.
