Abstract

A nonfluorescent low-cost, low-density oligonucleotide array was designed for detecting the whole coronavirus genus after reverse transcription (RT)-PCR. The limit of detection was 15.7 copies/reaction. The clinical detection limit in patients with severe acute respiratory syndrome was 100 copies/sample. In 39 children suffering from coronavirus 229E, NL63, OC43, or HKU1, the sensitivity was equal to that of individual real-time RT-PCRs.

摘要

设计了一种非荧光、低成本、低密度的寡核苷酸阵列,用于在逆转录(RT)-PCR后检测整个冠状病毒属。检测限为15.7拷贝/反应。严重急性呼吸综合征患者的临床检测限为100拷贝/样本。在39名感染冠状病毒229E、NL63、OC43或HKU1的儿童中,该阵列的灵敏度与单独的实时RT-PCR相同。
