Abstract

Methylation of RNA is normally monitored in purified cell lysates using next-generation sequencing, gel electrophoresis, or mass spectrometry as readouts. These bulk methods require the RNA from ~104 to 107 cells to be pooled to generate sufficient material for analysis. Here we describe a method—methylation-sensitive RNA in situ hybridization (MR-FISH)—that assays rRNA methylation in bacteria on a cell-by-cell basis, using methylation-sensitive hybridization probes and fluorescence microscopy. We outline step-by-step protocols for designing probes, in situ hybridization, and analysis of data using freely available code
