虽然原理上PCR需要以DNA作为模板，RNA不能直接被扩增，但是经过反转录酶的作用把RNA反转录成cDNA后，PCR法便可应用于RNA的解析了，这就是今天我们要介绍的RT-PCR技术。 RT—PCR技术灵敏且用途广泛 ...

or real-time RT–PCR. Fast and accurate, real-time RT–PCR has been critical in detecting, tracking and studying COVID-19. But what is it, and how does it work? Let us explain.

Real-time PCR is the favored method for measuring gene expression. Researchers benefit from a vast and growing choice of reagents and instruments for their experiments. Laura Bonetta reports.
