An improved, sensitive, specific, and rapid one-step reverse transcription loop-mediated isothermal amplification (LAMP) assay targeting the 5' untranslated region (UTR) was developed to detect hepatitis C virus (HCV) infection. Based on an accelerating primer (AP), the present assay, named AP-LAMP, has the advantages of rapidity and sensitivity over the routine LAMP method. The possible AP-based amplification pathway during the reaction was revealed by restriction enzyme digestion and eletrophoresis. The detection limit of the AP-LAMP assay was approximately 84 IU/ml, and no cross-detection was observed. The assay was evaluated further with 126 clinical specimens, and the results indicated the suitability and simplicity of the test as a rapid diagnostic tool for detection of HCV RNA.
一种改良的、敏感的、特异的、快速的一步逆转录环介导等温扩增（LAMP）检测方法，针对 5'非翻译区（UTR），用于检测丙型肝炎病毒（HCV）感染。基于加速引物（AP），本检测方法，命名为 AP-LAMP，在快速性和灵敏度方面优于常规 LAMP 方法。通过酶切和电泳揭示了反应过程中可能的基于 AP 的扩增途径。AP-LAMP 检测的检测限约为 84IU/ml，没有交叉检测。该检测方法进一步用 126 个临床标本进行了评估，结果表明该检测方法作为 HCV RNA 的快速诊断工具具有适用性和简单性。
