5-Methylcytosine (m5C) is a posttranscriptional RNA modification identified in both stable and highly abundant tRNAs and rRNAs, and in mRNAs. Many known or novel m5C sites have been validated by using advanced high-throughput techniques combined with next-generation sequencing (NGS), especially RNA bisulfite sequencing (RNA-BisSeq). Here we introduce an optimized RNA-BisSeq method by using ACT random hexamers to prime the reverse transcription of bisulfite-treated RNA samples to detect the m5C sites.
