  • Patent number: 6248534
    Abstract: The present invention provides a method of detecting RNA, comprising: (a) preparing cDNA to be measured and standard cDNA by reverse transcription of RNA as the subject of detection and standard RNA respectively; (b) adding different adapters respectively to the standard cDNA prepared at stepwise concentrations; (c) adding an adapter other than said adapters to the cDNA to be measured; (d) mixing and amplifying the adapter-tagged cDNAs obtained in the steps (b) and (c); (e) measuring the amount ratio of the cDNA measured to the standard cDNA; and (f) detecting said RNA from the measurement results.

  • Patent number: 6090556
    Abstract: The present invention relates to a method for quantitatively determining the expression of a gene, comprising providing at least two types of samples each containing a cDNA coding for the gene, adding a different adaptor to each of the cDNAs contained in the samples, mixing equal amounts of the samples each containing the adaptor-tagged cDNA, amplifying the resultant cDNAs and calculating an amount ratio between the amplified products.

  • Patent number: 5707807
    Abstract: This invention relates to a method for classifying (indexing) cDNA which has been reverse-transcribed from tissue- or cell-derived RNA, or DNA in a short period without duplication by using class-IIS restriction enzymes or a combination of a class-IIS and a class-II restriction enzymes. According to this invention, it is possible to analyse and diagnose variations such as tumors easily, correctly and promptly by comparing the analyzed pattern of genes expressed in a cell or tissue sample with the analyzed pattern of normal genes. This method is also applicable to the search and isolation of genes of physiologically active substances that are potential pharmaceuticals or causative genes of hereditary diseases, as well as the isolation of those genes that are useful for improving agricultural products.
