其它 | NA methylation catalyzed by methyltransferase (MTase) is a significant epigenetic process for modulating gene expression. Traditional methods to study MTase activity require a laborious and costly DNA labeling process. In this article, we report a simple, colorimetric, and label-free methylation-responsive DNAzyme (MR-DNAzyme) strategy for MTase activity analysis. This new strategy relies on horseradish peroxidase (HRP) mimicking DNAzyme and the methylation-responsive sequence (MRS) of DNA which can be methylated and cleaved by the MTase/endonuclease coupling reaction. |
