  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.

  本发明旨在提供一种预处理方法，使 RNA 能够得到及时、简单的检测。例如，通过向含有人类鼻黏膜的生物样本中添加铁离子和碳酸根离子，抑制存在于人类鼻黏膜中的乳铁蛋白引起的 RNA 降解活性。经预处理的生物样本可通过逆转录酶扩增 RNA 病毒基因。铁离子和碳酸根离子还能抑制人鼻黏膜中含有的溶菌酶 C 对逆转录酶的抑制作用。此外，最好在含有人鼻黏膜的生物样本中加入 SDS，以去除 RNA 病毒的包膜。
