RNA的甲基化通常在纯化细胞裂解物中监测,使用下一代测序,凝胶电泳或质谱作为读数。这些批量方法需要将约104至107个细胞的RNA汇集在一起,以产生足够的分析材料。在这里,我们描述了一种方法-甲基化敏感RNA原位杂交(MR-FISH),该方法使用甲基化敏感杂交探针和荧光显微镜在细胞-细胞的基础上分析细菌中的rRNA甲基化。我们概述一步一步的协议设计探针,原位杂交,并使用免费提供的代码分析数据。
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 ~104to 107cells 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.
