Detection and discrimination of recombinant plasmid encoding hepatitis C virus core/E1 gene based on PNA and double-stranded DNA hybridization.

本文报道一种基于肽核酸（PNA）探针与双链DNA杂交的电化学生物传感器，用于直接检测并区分编码丙型肝炎病毒（HCV）core/E1基因的双链重组质粒，无需对靶质粒进行变性。该目标通过金电极修饰6-巯基-1-己醇（MCH）并自组装半胱氨酸偶联的20聚PNA探针单分子层实现，探针序列互补于HCV core/E1区域。当电极接触互补双链质...
