Extraction protocol |
The gametes and embryos were frozen at 70 below zero or subjected to immediate genomic extraction procedures. Genomic DNA was extracted by QIAamp DNA Mini Kit(QIAGEN) following the protocol of DNA Purification from Tissues with the cell lysis time adjusted depending on different samples. Genomic DNA spiked with 0.5% unmethylated Lambda DNA (Promega) was sonicated into 100-500bp. Fragmented DNA was then subjected to end repair,dA tailing, ligation with the end repair enzyme mix (NEB), Klenow 3´-5´ exo- (NEB) and T4 DNA ligase (NEB), respectively. Adapter-ligated DNA was recovered by 2% agarose gel electrophoresis, and bisulfite conversion was performed using the EZ DNA methylation-Gold kit (Zymo Research) according to the instruction manual. Bisulfite-treated DNA was amplified with KAPA HiFi HotStart Uracil+ ReadyMix. Amplified DNA was recovered by 2% agarose gel electrophoresis.
