title: Whole genome bisulfite sequencing of rat carotid body
design: WGBS: Firstly, the genomic DNA spiked with lambda DNA were fragmented to 200-400 bp. The DNA fragments were bisulfite treated to generate single strand DNA (ssDNA). During the bisulfite conversion, unmethylated cytosine were converted into uracil, while methylated cytosine stayed unchanged. Methylation sequencing adapters were ligated, followed by double strand DNA synthesis. The library was ready after size selection and PCR amplification.
