Abstract Provided is a method for detecting an RNA virus in a biological sample, the method comprising: (1) a step for preparing a sample solution containing a biological sample, a protease, a nucleic acid that does not become a target of nucleic acid amplification, and at least one additive selected from the group consisting of chaotropic reagents and surfactants; (2) a step for preparing a nucleic acid amplification reaction solution containing the sample solution prepared in step (1) and containing a polypeptide having reverse transcriptase activity and DNA polymerase activity or a polypeptide having reverse transcription activity and a polypeptide having DNA polymerase activity; and (3) a step for amplifying a nucleic acid of the RNA virus in the reaction solution prepared in step (2). L'invention concerne un procédé de détection d'un virus à ARN dans un échantillon biologique, le procédé comprenant les étapes suivantes : (1) préparation d'une solution d'échantillon contenant un échantillon biologique, une protéase, un acide nucléique qui ne devient pas une cible d'amplification d'acide nucléique, et au moins un additif choisi dans le groupe constitué par les réactifs chaotropes et les agents tensioactifs ; (2) préparation d'une solution réactionnelle d'amplification d'acide nucléique contenant la solution d'échantillon préparée à l'étape (1) et contenant un polypeptide ayant une activité de transcriptase inverse et une activité d'ADN polymérase ou un polypeptide ayant une activité de transcription inverse et un polypeptide ayant une activité d'ADN polymérase ; et (3) amplification d'un acide nucléique du virus ARN dans la solution réactionnelle préparée à l'étape (2). 生体試料中のRNAウイルスを検出する方法であって、以下の工程: (1)生体試料と、タンパク質分解酵素、核酸増幅の標的とならない核酸、カオトロピック試薬ならびに界面活性剤からなる群から選択される少なくとも一つの添加剤、を含む試料液を調製する工程、 (2)前記工程(1)で調製された試料液と、逆転写活性を有するポリペプチド及びDNAポリメラーゼ活性を有するポリペプチド、又は逆転写酵素活性及びDNAポリメラーゼ活性を有するポリペプチド、を含む核酸増幅反応液を調製する工程、及び (3)前記工程(2)で調製された反応液中で前記RNAウイルスの核酸を増幅する工程、 を包含する、方法が提供される。
