肺炎球菌是全球感染性疾病的重要病原菌,尤其在儿童、老年人和免疫缺陷患者中危害严重,且抗生素耐药肺炎链球菌日益增多,因此需要简单、快速、特异的检测方法。本研究采用细菌系统进化指数富集(SELEX)技术,以活菌为靶标筛选出可特异性识别肺炎链球菌(Streptococcus pneumoniae)的DNA适配体,并将其整合到氧化石墨烯(G...

作者报道了一种基于环介导等温扩增(LAMP)并引入南极热敏感尿嘧啶-DNA糖基化酶(AUDG)的核酸检测方案,可同时实现核酸检测与消除携带污染。该方法采用侧流层析(LFA)格式,无需标记引物或探针,可避免两条标记引物之间或标记引物与探针之间非特异杂交导致的假阳性。LAMP扩增与AUDG消化在同一管中完成,并通过封闭管反应降低携带污染...
