    摘要: A method for detecting specific nucleic acid sequences (a single sequence and/or a mixture of nucleic acid sequences) which are present in a biological sample, comprising at least one enzymatic amplification. Detection is carried out, after placing the biological samples in a solution in order to extract the nucleic acid, by enrichment with target sequences by putting the biological samples into contact with at least one pair of appropriate triggers, followed by at least one appropriate dilution of the obtained enrichment amplifying solution, and by putting a fraction of this solution into contact with at least one pair of triggers, followed by the detection of the obtained double-strand target nucleic acid copies. Applications in the diagnosis of genetic, infectious and tumoral diseases, in checking biological samples and in cell typing etc.

    摘要: A method for preparing double stranded RNA, wherein the simultaneous transcription of two complementary DNA sequence strands in a single reaction mixture is preformed, and the two resulting transcripts are immediately hybridized. The double stranded RNA fragments may be used for detecting and/or assaying nucleic acid target sequences in a biological sample.

    摘要: Process for RNA synthesis consisting in successively condensing necleosides for the formula (1) in which R.sup.1 is a puric pyrimidic optionally protected base, R.sup.2 is a leaving group such as the dimethoxytrityl radical, R.sup.3 is a phosphorus-containing radical, for example, phosphoramidite and R.sup.4 is a trialkylsilyl radical. The RNA obtained is then subjected to a protective treatment with a reagent of the formula (II), for example N(C.sub.2 H.sub.5).sub.3,3HF, to eliminate R.sup.4 protective groups of the 2' hydroxyl groups. Such reagent provides full deprotection in about ten hours, with an RNA of great length, for example, having more than 50 bases.
