title: GSM5848490: Feeder-free PSC; Homo sapiens; Bisulfite-Seq
library_construction_protocol: Genomic DNA was isolated from ESCs with the DNeasy Blood & Tissue kit (Qiagen), fragmented into 200-400 bp by sonication (Covaris), and was processed for bisulfite modification using EZ DNA methylation Gold Kit (Zymo). The libraries were prepared using Scale Methyl-DNA Lib Prep Kit for Illumina (ABclonal).
