Abstract: The amount of an RNA transcription product amplified in an RNA amplification process is measured using a nucleic acid probe labeled with an intercalating fluorescent dye. The RNA amplification process comprises the steps of using at least two sets of primer pairs comprising a first primer and a second primer (in which one of these primers carries a promoter sequence added to the 5? end thereof), both of which have high hybridization efficiency to a nucleic acid sequence that is homologous to or complementary to each norovirus genotype RNA; forming a double-stranded DNA containing the promoter sequence with a reverse transcriptase; forming an RNA transcription product with an RNA polymerase by using the double-stranded DNA as a template; and forming the double-stranded DNA by successively using the RNA transcription product as a template in the DNA synthesis with the reverse transcriptase.

Abstract: The present invention provides a combination of oligonucleotides preferable for composing a gene testing reagent capable of detecting all subtypes of norovirus rapidly and with high sensitivity. More specifically, the present invention provides a detection method in which only norovirus is specifically amplified and an oligonucleotide that binds to a specific site of norovirus, by using a primer having a sequence that is homologous or complementary to a base sequence specific for norovirus and is located at a position subject to minimal mutation according to subtype.
