  • 临床高灵敏度和高特异性
  • 信号扩增简单,无需靶向扩增
  • 结果清楚、客观

Product Details

digene HC2 CT-GC Dual ID DNA Test用于筛选Chlamydia trachomatis (CT)和Neisseria gonorrhoeae (GC)感染的病群。

Performance

digene HC2 CT-GC Dual ID DNA Test与一些较复杂的靶向扩增方法相比,在临床上有更高的灵敏度和特异性(参见下表)。

Principle

digene HC2 CT-GC Dual ID DNA Test是一种核酸杂交分析,通过微孔板化学发光检测进行信号扩增。含有靶标DNA的样本与特异性CT或GC RNA鸡尾酒探针结合。获得的RNA-DNA杂交物被捕获到包被有特异性抗体的微孔板表面上。固定的杂交物与联结有碱性磷酸酶的特异性抗体反应,再通过化学发光底物检测。每个抗体上都连有几个碱性磷酸酶分子。多重联结抗体结合到每个捕获杂交物上,产生后续的信号扩增。由于底物被结合的碱性磷酸酶切割,激发光在光度计上被检测为相对光单位(RLUs)。光强度指示样本中是否存在靶标DNA。

Procedure

digene HC2 CT-GC Dual ID DNA Test试剂盒包含所需的探针和试剂,通过基于化学发光信号扩增的体外核酸杂交分析,筛选Chlamydia trachomatis (CT)或Neisseria gonorrhoeae (GC)。CT和GC鸡尾酒探针包含的探针混合物用于去除或减少来自人细胞、其他细菌种类、除Chlamydia trachomatis的Chlamydia类或除Neisseria gonorrhoeae的Neisseria类的DNA序列的交叉反应。

使用digene HC2 DNA Collection Device或digene Female Swab Specimen Collection Kit收集和运输用于digene HC2 CT-GC Dual ID DNA Test的子宫颈样本。

digene HC2 CT-GC Dual ID DNA Test的操作流程非常简单,从变性到杂交和杂交捕获。 变性之后直到样本检测的流程可在Rapid Capture System上完全自动化。检测在光度计上手动完成。

Applications

digene HC2 CT-GC Dual ID DNA Test用于分别定量检测同一子宫颈样本中的Chlamydia trachomatis (CT)和Neisseria gonorrhoeae (GC) DNA。该试剂盒可分别检测CT和GC,也可只检测其中一个。digene HC2 CT/GC DNA Test检测为阳性时,可使用该产品进行后续检测,以区分样本中的CT和GC。

digene HC2 CT-GC Dual ID DNA Test经验证用于确定有症状或无症状的妇女是否感染Chlamydia trachomatis (CT)和/或Neisseria gonorrhoeae (GC) 。
