whole-genome bisulfite sequencing data at IGHM region in Nalm6 cell line
200ng genomic DNA of Nalm6 was sheared around 400bp using Covaris LE220 and followed by bisulfite conversion using EZ DNA Methylation-Gold Kit. The fragmented, bisulfite-converted single-strand DNA was tailed and ligated of truncated adapter one to 3 end, primer extended and truncated of adapter two at the bottom strand only. Finally, the library was purified and enriched by 6 cycles of index PCR amplification then sequenced paired-end 151 cycles on Illumina NovaSeq 6000.
