产品详情

artus CT/NG QS-RGQ Kit是即用型real-time PCR实验试剂盒,可用于QIAsymphony RGQ系统。该试剂盒包含针对沙眼衣原体(chlamydia trachomatis,CT)质粒和基因组DNA,以及淋病奈瑟菌(Neisseria gonorrhoeae, NG)基因组DNA的直接定性检测而优化的所有必备试剂。

绩效

artus CT/NG QS-RG试剂盒诊断的敏感度和特异性与Abbott CT/NG assay进行了比较。相对于Abbott CT/NG assay,artus CT/NG QS-RGQ试剂盒对CT的诊断的特异性是99.8%,敏感度是98.1%;对NG诊断的特异性是99.8%,敏感度是96.3%。

对拭子和尿液具有出色的检测能力

对于拭子,考虑到样品的纯度,通过在eNAT基质中加入倍比稀释的沙眼衣原体和淋病奈瑟菌细胞并在QIAsymphony SP上进行提取,测定CT/NG QS-RGQ Kit的分析检测极限(LOD)。根据LOD数据,检测到5 EB/ml的沙眼衣原体和3 CFU/ml的淋病奈瑟菌的几率是95%(参见下表)。

对于尿液,考虑到样品的纯度,通过在包含eNAT稳定剂的尿样中加入梯度稀释的沙眼衣原体和淋病奈瑟菌细胞溶液细胞,测定artus CT/NG QS-RGQ Kit的分析检测极限(LOD)。根据LOD数据,检测到7.65 EB/ml的沙眼衣原体和6.89 CFU/ml的的淋病奈瑟菌的几率是95%(参见下表)。

出色的检测阈限
病菌 拭子 尿液
C. trachomatis 5 EB/ml 8 EB/ml
N. gonorrhoeae 3 CFU/ml 7 CFU/ml

原理

artus CT/NG QS-RGQ Kit构成了一套即用型的系统,其通过QIAsymphony SP核酸提取纯化分析仪进行样品制备和建立实验,并通过Rotor-Gene Q实时荧光定量PCR分析仪上进行real-time PCR反应,检测沙眼衣原体和淋病奈瑟菌DNA。CT/NG RG Master预混液的试剂和酶能够特异性的扩增沙眼衣原体隐蔽性质粒的86 bp区域及其基因组的66 bp序列,以及淋病奈瑟菌基因组的74 bp靶序列,以便在Rotor-Gene Q实时荧光定量PCR分析仪的绿色和橙色荧光通道上直接检测特异性扩增子。

这一试剂盒也提供了一套异源扩增体系,用于确定可能的PCR抑制物。其检测方法为,通过Rotor-Gene Q实时荧光定量PCR分析仪上的黄色荧光通道检测内参(IC)。这一内参对照并不会降低CT/NG PCR的分析检测极限。该试剂盒还提供了外部的阳性/阴性对照实验(CT+/NG-对照和NG+/CT-对照)和无模板的对照实验。

程序

用于检测沙眼衣原体和淋病奈瑟菌DNA的QIAsymphony RGQ完整工作流程解决方案包括用于样品制备的QIAsymphony SP Kit和QIAsymphony DSP Virus/Pathogen Midi Kit,用于反应体系构建的QIAsymphony AS,以及用于Rotor-Gene Q实时荧光定量PCR分析仪的artus CT/NG QS-RGQ Kit试剂盒。这一系统使用完整的CE-IVD相容的工作流程对病原体DNA进行可靠地检测。

该试剂盒也可以与Rotor-Gene Assay Manager一起使用,自动化的解释实验结果。

应用

artus CT/NG QS-RGQ Kit能够快速、敏感的检测阴道、子宫颈和男性尿道拭子以及男性和女性尿样中的沙眼衣原体质粒和基因组DNA,以及淋病奈瑟菌基因组DNA。

artus CT/NG QS-RGQ Kit设计用于QIAsymphony RGQ,可提供从样品的准备到结果分析、符合CE-IVD要求的工作流程。
