title: GSM3704260: M-3-4; Arabidopsis thaliana; Bisulfite-Seq
library_construction_protocol: genomic DNA extraction using DNeasy Plant kit (Qiagen, Germany). Genomic DNA Sonicated to 100-300 bp fragments and purified with MiniElute PCR Purification Kit (Qiagen, Germany), incubated at 20 ℃ after add End Repair Mix. Then purified and added a single 'A' nucleotide to the 3' ends of the blunt fragments, purified again and add Methylated Adapter to the 5' and 3' ends of each fragment. Then fragments with 300bp-400bp size-range were purified with QIAquick Gel Extraction kit (Qiagen, Germany) and subjected to bisulfite treatment by using Methylation-Gold kit (ZYMO). Followed with PCR and gel purification (350bp-400bp range fragments were selected). Qualified libraries sequenced pair end on the HiSeq X-ten system.
