成果采用磁珠法核酸提取对目标病原体核酸进行提取纯化,核酸提取过程采用液体转移的方式,主要包括裂解、结合、清洗、洗脱四个步骤,纯化后的核酸被自动转移至扩增检测区进行实时荧光定量PCR步骤,根据荧光曲线,判断检测结果。产品近似立方体,长宽高约为30cm,系统整体质量约为15Kg,主要包括封闭式卡盒、一体化检测装置和配套的PC端控制软件三部分结构。系统主要功能为全自动磁珠法核酸提取和多重实时荧光PCR扩增检测,经优化后可在1小时内完成“样本输入—结果输出”全过程,最多可进行6重检测。检测过程全封闭全自动,在卡盒中完成,避免了交叉污染。
该成果提供一种病原体现场快速检测系统两层结构,上层结构包含上层底板,水平轴控制组件和竖直轴控制组件,下层结构包含下层底板,磁分离组件和热组件,荧光检测组件。配合封闭式病原体检测卡盒,卡盒固定安装在系统中,通过PC端设计的软件控制系统对卡盒中液体的操作,可自动完成基于磁珠法的病原体快速荧光检测。整个系统操作简单,安全,并且检测结果以报告的形式直观展现。
本产品样机在江苏疾控中心和浙江疾控中心进行过多种临床样本检测试验,检测样本种类有:粪便、唾液、脑脊液等,检测病原体种类有:腺病毒、艰难梭菌、大肠杆菌等。同一样本,使用本系统检测结果与手工核酸提取+商用荧光定量PCR仪(Roche LightCycler96)检测结果相当(Ct值)。本产品正用于非典型性肺炎新冠病毒快速检测研究。
