摘要： A method for preparing a cDNA from a mRNA using a reverse transcriptase wherein reverse transcription is performed at a temperature at which the mRNA does not take a secondary structure, for example, at a temperature of 45° C. or more. The method is performed, for example, using a heat-labile reverse transcriptase in the presence of a substance exhibiting chaperone function having chaperone function such as saccharides. The method is performed, for example, in the presence of metal ions necessary for activation of the reverse transcriptase and a chelating agent for the metal ions such as a deoxynucleotide triphosphate. The method is capable of reverse transcription over the full length of mRNA template even if the mRNA is a long chain mRNA and, as a result, producing a full length cDNA.

摘要： The present invention is to provide a pretreatment method that allows RNA to be detected promptly and simply. RNA degradation activity due to lactoferrin present in the human rhinal mucosa is inhibited, for example, by adding iron ion and carbonate ion to a biological sample that contains the human rhinal mucosa. With the pretreated biological sample, an RNA virus gene can be amplified by a reverse transcriptase. Iron ion and carbonate ion can also inhibit reverse transcriptase inhibition due to lysozyme C contained in the human rhinal mucosa. Further, it is preferable to remove the envelope of the RNA virus by adding SDS to the biological sample that contains the human rhinal mucosa.
