摘要:
非洲猪瘟病毒(African swine fever virus, ASFV)是近年来流行的一种主要致病病毒,对我国的国民经济生活造成了严重影响。本研究以非洲猪瘟病毒的编码保守蛋白p54基因序列片段为检测目标,结合点亮 Spinach RNA适配体的开关功能,设计了Spinach-p54的嵌合式RNA适配体。其特异地结合目标序列并产生荧光,实现了在RNA水平上对非洲猪瘟病毒的快速检测。研究结果表明,核酸适配体浓度200 nmol/L,反应温度为37 ℃,该方法检出限为200 nmol/L,线性范围为200~400 nmol/L。该方法特异性强,操作简单,灵敏度高等特点,可用于市场和养殖场的现场快速检测。
