HBV-DNA的生物素寡聚核苷酸探针快速检测

Rapid Detection of HBV-DNA by Using Biotinylated Oligonucleotide Probe

本文建立一种快速HBV-DNA检测方法。此法是基于生物素标记的寡聚核苷酸与硝酸纤维素滤膜上的靶DNA杂交,然后通过Streptoavidin-碱性磷酸酶偶联体及生色底物进行检测。本文研究了此法的实用性,表明对于实验室及临床的HBV-DNA检测,此法是一种快速(4小时)、灵敏(1—10pg)、特异、方便的方法。

A rapid method for detection of HBV-DNA was developed. This assay was based on the hybridization of biotinylated oligonucleotide probe to target DNA immobolized on nitrocellulose membrane which was then incubated with avidin-alkaline phosphatase conjugator and measured with chromogenic substrates. The practicality of the method was investigated. It was found that the method was fast (4hr),sensitive(1-10pg)and expedient for laboratory and clinical detection of HBV-DNA.
