title: GSM5115781: SPERM49; Macaca fascicularis; Bisulfite-Seq
library_construction_protocol: A total amount of 5.2 microgram genomic DNA spiked with 26 ng lambda DNA were fragmented by sonication to 200-300bp with Covaris S220, followed by end repair and adenylation. Cytosine-methylated barcodes were ligated to sonicated DNA as per manufacturer s instructions. Then these DNA fragments were treated twice with bisulfite using EZ DNA Methylation-GoldTMKit (Zymo Research). And the resulting single-strand DNA fragments were PCR amplificated using KAPA HiFi HotStart Uracil + ReadyMix (2X). Library concentration was quantified by Qubit 2.0 Flurometer (Life Technologies, CA, USA) and quantitative PCR, and the insert size was checked on Agilent Bioanalyzer 2100 system. The clustering of the index-coded samples was performed on a cBot Cluster Generation System using TruSeq PE Cluster Kit v3-cBot-HS (Illumia) according to the manufacturer s instructions. After cluster generation, the library preparations were sequenced on an Illumina Hiseq 2000/2500 platform.
