ONT测序平台根据监测单个分子在合成聚合物膜嵌入的纳米孔中穿过时引起的电流变化直接测序DNA或RNA,修饰碱基穿孔产生的电流可能与对应的经典碱基有所不同,因此可以根据检测到的电流差异来检测包括m6A在内的修饰碱基【12,13】。自那时起,已经有十余种计...
MeRIP-seq 技术将甲基化DNA 免疫共沉淀(methylated DNA immunoprecipitation,MeDIP) 技术、RNA 结合蛋白免疫共沉淀(RNA immunoprecipitation,RIP)技术和RNA 测序(RNA sequencing,RNA-seq) 技术组合起来,高精度地检测全基因组(或全转录组)范围内的RNA 甲基化。MeRIP-seq 技术采用免疫共沉淀方法,即甲基化RNA 特异性抗体...
上图来自以下文献 Epitranscriptome sequencing technologies: decoding RNA modifications https://www.nature.com/articles/nmeth.4110 m6A是其中最常见,数量最多的一种转录后修饰,不仅在mRNA上存在,在tRNA, rRNA, lncRNA上也都存在,只不过研究最多的是mRNA上的m6A。m6A这个名字来源于发生甲基化修饰的位置 腺苷酸第6...
