{"doi":"10.1016/j.xpro.2022.101937","title":"A transcription-based approach to purify R-loop-containing plasmid DNA templates in vitro","abstract":"To study the direct effects of R-loops on DNA replication and other DNA-templated processes in vitro, R-loop-containing DNA templates need to be prepared efficiently and to near homogeneity. Here, we describe a simple transcription-based approach to form R-loops on plasmid DNA templates in vitro. We detail steps to transcribe a DNA sequence element with a high propensity to form co-transcriptional R-loops using T7 RNA polymerase. We describe nucleolytic digestion of free RNA, deproteinization, and repurification of R-loop-containing templates via gel filtration.
