Abstract: The present invention provides a detection method for detecting norovirus, using an RNA amplification process comprising the steps of : producing a cDNA with an RNA-dependent DNA polymerase using a specific sequence of norovirus genome RNA as a template, as well as a specifically defined first primer having a sequence homologous to said specific sequence, and a specifically defined second primer having a sequence complementary to said specific sequence, thereby forming a double-strand RNA-DNA, wherein either the first primer or the second primer has a sequence in which a promoter sequence of an RNA polymerase has been added to its 5' end; degrading the RNA portion of said double-strand RNA-DNA by ribonuclease H, thereby producing a single-strand DNA; and producing a double-strand DNA having said promoter sequence capable of transcribing the RNA composed of the specific sequence of the RNA or the sequence complementary to said specific sequence of the RNA with a DNA-dependent DNA polymerase using said single-strand DNA as a template; wherein, the double-strand DNA produces an RNA transcription product in the presence of the RNA polymerase, and said RNA transcription product serves as a template for the subsequent cDNA synthesis with the RNA-dependent DNA polymerase.

Abstract: A novel transcriptome analyzing method, provision of a gene found by this method and a protein encoded by said gene. A method for determining whether or not a continued arbitrary DNA sequence existing in the genome of an arbitrary biological species, of which the nucleotide sequence is already known but its possibility of being an expressed region is unclear (specific region), which comprises detecting whether or not a nucleotide sequence that corresponds to the nucleotide sequence of the region is present in the RNA of the biological species, by means of RT-PCR in combination with NASBA and detection using fluorescent labelled oligonucleotide probes.

Abstract: The object of the present invention is to provide a method for discriminating between liver cirrhosis and chronic hepatitis by serodiagnosis using a simple enzyme immunoassay method without performing histopathological examinations by biopsy and so forth. The present invention discloses an enzyme immunoassay method for cholinesterase using a monoclonal antibody, a method for detecting Aleuria aurantia lectin-reactive cholinesterase using a monoclonal antibody and Aleuria aurantia lectin, and a method for discriminating between liver cirrhosis and chronic hepatitis on the basis of those results.

Abstract: Monoclonal antibodies recognizing gp130 protein and binding to the protein to inhibit IL-6 functions completely (that is to the same level as that is the absence of IL-6) when present in enough amount; a hybridoma producing the monoclonal antibody; a process for production of the monoclonal antibodies using the hybridoma; and an inhibitory agent for inhibition of physiological actions of IL-6 comprising the monoclonal antibodies.
