DNA quantification is important in the research of life sciences. In an independent quantification process, the extracted part of a DNA sample is usually difficult to be recycled for further use while the widely used real-time PCR is used to count the copies with certain sequences. Based on the popular multiple displacement amplification (MDA), we proposed and performed quantitative real-time MDA to obtain the information of template amount based on fluorescence signals while amplifying whole-genome DNA. The detection limit of real-time MDA was as low as 0.5 pg μl−1 (5 pg DNA input), offering the whole-genome research a promising tool to quantify the entire DNA during amplification without sacrificing sample completeness or introducing redundant steps.

通过定量实时多重位移扩增在全基因组扩增过程中定量基因组 DNA

DNA 定量在生命科学研究中非常重要。在独立的定量过程中,DNA样本的提取部分通常很难回收再利用,而广泛使用的实时PCR用于对某些序列的拷贝进行计数。基于流行的多重位移扩增(MDA),我们提出并进行了实时定量MDA,在扩增全基因组DNA的同时,根据荧光信号获取模板量信息。实时MDA的检测限低至0.5 pg μl -1(5 pg DNA输入),为全基因组研究提供了一种很有前途的工具,可以在扩增过程中量化整个DNA,而不会牺牲样品完整性或引入冗余步骤。
