Abstract
Given the crucial role of DNA damage in human health and disease, it is important to be able to accurately measure both mitochondrial and nuclear DNA damage. This article describes a method based on a long-amplicon quantitative PCR–based assay that does not require a separate mitochondrial isolation step, which can often be labor-intensive and generate artifacts. The detailed basic protocol presented here is newly revised, with particular attention to application in Homo sapiens, Rattus norvegicus, and Caenorhabditis elegans resulting from changes in availability of PCR reagents. Optimized extraction support protocols are also described for high-quality DNA from multiple rat tissues for which these procedures had not previously been described. © 2018 by John Wiley & Sons, Inc.
新修订的基于定量pcr的线粒体和核DNA损伤检测方法
鉴于DNA损伤在人类健康和疾病中的关键作用,能够准确测量线粒体和核DNA损伤是很重要的。本文描述了一种基于长扩增子定量pcr的方法,该方法不需要单独的线粒体分离步骤,这通常是劳动密集型的,并且会产生伪影。本文提出的详细基本方案是新修订的,特别注意在智人、褐家鼠和秀丽隐杆线虫中的应用,这是由于PCR试剂可用性的变化造成的。优化的提取支持协议也描述了高质量的DNA从多个大鼠组织,这些程序以前没有描述过。©2018 by John Wiley &儿子,Inc。
