逆转录-聚合酶链式反应(RT-PCR)被广泛用于检测小样本中低丰度的mRNAs。研究基因表达所需要的对它们水平的准确定量测量可以通过RT-竞争性PCR来执行,这是一种依赖于在扩增反应中添加已知数量的cDNA竞争分子的方法。在这里,我们证明了这种方法可以在任何实验室用最少的分子生物学设备很容易地建立起来,并且无论是同源竞争对手还是异源竞争对手,只要序列长度相对于靶标有很小的差异,就可以准确地定量特定的mRNA。我们建议在RT步骤中使用一种耐热的逆转录酶来克服目的基因合成效率的问题。此外,为了获得可靠的测量结果,我们建议执行四个与竞争对手的数量侧翼的目标mRNA浓度的聚合酶链式反应。
Reverse transcription-polymerase chain reaction (RT-PCR) is widely used to detect low abundance mRNAs in small samples. Accurate quantitative measurement of their level, as required for the study of gene expression, can be performed by RT-competitive PCR, a method that relies on the addition of known amounts of a cDNA competitor molecule in the amplification reactions. Here we demonstrate that this method can be easily set up in any laboratory with a minimum of equipment in molecular biology, and that either homologous or heterologous competitor, with a small difference in sequence length relative to the target, can be used to quantify specific mRNA accurately. We propose the utilization of a thermostable reverse transcriptase in the RT step to overcome the problem of the efficiency of target cDNA synthesis. In addition, to obtain reliable measurements, we recommend performing four PCR reactions with amounts of competitor flanking the concentration of the target mRNA.
