title: GSM8207739: 2 Lifetime, rep 4, 1620 days; Mus musculus; Bisulfite-Seq
library_construction_protocol: DNA was extracted from the sorted cells and then bisulfite treated using an EZ DNA Methylation-Direct kit (Zymo Research). Bisulfite-modified DNA sequencing libraries were generated using the EpiGenome kit (Epicentre) according to the manufacturer's instructions. Bisulfite-modified DNA libraries were sequenced using Illumina NovaSeq 6000 systems
