项目摘要
Preparation of high-quality cDNA is needed for functional analysis of gene function. However, reverse transcription PCR, an exponential amplification method causes a bias to majority of RNA molecules, because the reaction rate of enzymatic reaction depends on the concentration of the substrates. We developed a novel method for amplification of ultralow amount RNA by addition of dummy substrate RNA(Chum-RNA) into in vitro transcription and RT reaction system. Chum-RNA increases virtual concentration of substrate in the system, and the enzymes can catalyze the reaction for a very small number of RNA molecules. This novel technology enabled us to construct a high-quality cDNA library which reflects the original distribution of mRNA molecules from a single cell amount of RNA. Here, we report that this technology can be applied to Microarray analysis and Real time PCR method.
基因功能分析需要高质量cDNA的制备。然而,逆转录PCR,一种指数扩增方法,会导致对大多数RNA分子的偏倚,因为酶促反应的反应速率取决于底物的浓度。我们在体外转录和RT反应体系中加入虚拟底物RNA(Chum-RNA),建立了一种扩增超低量RNA的新方法。Chum-RNA增加了系统中底物的实际浓度,并且酶可以催化非常少量的RNA分子的反应。这项新技术使我们能够构建一个高质量的cDNA文库,该文库反映了来自单细胞量RNA的mRNA分子的原始分布。在此,我们报道该技术可应用于微阵列分析和真实的时间PCR方法。
