    摘要: A transcriptional sequence method whereby a high SN ratio can be obtained in sequence analysis with the use of capillary and longer and more accurate base sequence data can be obtained in a single reaction. More specifically, a method of determining a DNA base sequence involving the step of obtaining a nucleic acid transcription product with the use of an RNA polymerase, a template DNA having a promoter sequence for the RNA polymerase and substrates of the RNA polymerase. The substrates of the RNA polymerase involve a 3'-deoxynucleotide derivative. The RNA polymerase is a mutant RNA polymerase derived from a wild type RNA polymerase by substitution of at least one amino acid or deletion of at least one amino acid. The substitution and/or deletion of the amino acid(s) are performed so that the mutant RNA polymerase has an enhanced capability of incorporating the 3'-deoxynucleotide derivative as a substrate compared with the corresponding wild type RNA polymerase.

    摘要: 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.

    摘要: This invention relates to the use of a eukaryotic or prokaryotic DNA- directed RNA polymerase of a class that synthesizes cellular RNA, in a process for the amplification of a specific nucleic acid sequence or of its complement. It also relates to a new process for amplifying a specific nucleic acid sequence. The process includes one or more reactions which may take place in a single reaction vessel. In one instance, in a first reaction, the process includes providing a first RNA polymerase which uses a DNA first template to synthesize an RNA first template, and, in a second reaction, providing the RNA first template and a number of other reagents such that the reagents use the RNA first template to synthesize a DNA second template and an RNA second template. Thereafter a cycle ensues in which the reagents use the RNA second template to synthesize a DNA third template and multiple copies of the RNA second template. The RNA second template is the specific nucleic acid sequence or its complement. This invention includes a kit containing the reagents of this invention.

    摘要: The present invention relates to an improved method for the amplification of nucleic acid.
    The invention is characterized in that ribonucleotides are introduced during amplification that weaken normal basepairing. Preferably the ribonucleotides are inosine-triphosphate nucleotides which partly substitute guanine-triphosphate nucleotides normally present in the amplification reaction mixture. The incorporation of nucleotides, during amplification, that weaken normal base pairing prevents the formation of secondary structures in the amplificate. The efficiency of the amplification is thereby increased. The introduction, during amplification, of nucleotides that weaken normal base pairing also results in an improved sensitivity during detection of the amplified nucleic acid, when the detection method comprises the hybridization of the amplified nucleic acid to a complementary sequence.

    摘要: An assay and method of use thereof for amplification and detection of target nucleic acids in patient samples, which is rapid, simple and accurate is described. The assay and method utilizes any one of a variety of amplification methods, in combination with primers immobilized onto either the container containing the patient sample, such as a microtiter well plate, or a dipstick which is readily immersible into the container. Amplification occurs in the presence of both the first, immobilized primer and a second, labelled primer which hybridizes to the target nucleic acid in the opposite direction to the first. Examples demonstrate the effectiveness of the method in detecting a specific species of mycoplasma, as well as the gene characteristic of cystic fibrosis.

    摘要: Specific nucleic acid sequences are amplified through the use of transcribable hairpin probes. The probe comprises a single stranded self-­complementary sequence which, under hybridizing conditions, forms a hairpin structure having a functional promoter region, and further comprises a transcribable sequence extending from the 5′ end of the hairpin sequence and a probe sequence which may be comprised in the transcribable 5′ sequence or in a sequence extending from the 3′ end of the hairpin sequence. The hairpin form of the probe is transcribable in the presence of a suitable RNA polymerase and appropriate ribonucleoside triphosphates (rNTPs). Amplification is accomplished by hybridizing the desired target nucleic acid sequence with the transcribable probe, transcribing substantially only probe which has become hybridized to the sequence of interest, and allowing transcription to proceed until a desired amount of RNA transcription product has accumu­lated. Optional second stage amplification of the RNA transcripts can produce higher levels of amplification. The amplification method is particularly useful in assays for the detection of particular nucleic acid sequences.
