genomic DNA

Extraction protocol

Library construction protocol: Genomic DNA (1.5~5µg) was fragmented to 100-500 bp using a Covaris S2. Purified DNA fragments were end-repaired. After A-tailing, the DNA fragments were ligated with methylated paired-end adapters. Adapter-attached DNA fragments of 300-400 bp, which contain 150-250 bp genomic DNA inserts, were gel-purified. The purified DNA fragments were subjected to two cycles of sodium bisulfite conversion using the EpiTect Bisulfite kit (Qiagen). Adapter-attached, bisulfite-converted DNA molecules were enriched by PCR using PfuTurboCx Hotstart DNA polymerase (Stratagene). The PCR amplified DNA fragments were subjected to a second gel size selection to remove PCR primers and adapter dimers. The enriched library was quantified using a Qubit fluorometer and Quant-iT dsDNA HS Assay Kit. Library sequencing was performed using 101 BP PE Illumina technology.
