Abstract

Reverse transcriptase-polymerase chain reaction (RT--PCR) has been widely utilized for both the qualitative and quantitative assessment of the levels of specific mRNA transcripts in living systems. Quantitation of specific transcripts has often proved to be problematic because of the difficulty associated with relating the PCR-amplified product to the starting cDNA representing the mRNA of interest. We have overcome these difficulties and have developed a competitive PCR assay employing the property of electrochemiluminescence for the detection of PCR products. This assay possesses the dual advantage of being both nonradioactive and highly sensitive.

定量分析特定的mRNA转录物使用竞争性PCR分析与电化学发光检测。
逆转录聚合酶链反应(RT—PCR)已被广泛用于生物系统中特定mRNA转录物水平的定性和定量评估。特异性转录本的定量常常被证明是有问题的,因为很难将pcr扩增产物与代表感兴趣mRNA的起始cDNA相关联。我们已经克服了这些困难,并开发了一种具有竞争力的PCR分析,利用电化学发光的特性来检测PCR产物。这种测定法具有无放射性和高灵敏度的双重优点。
