Single-Cell Bisulfite Sequencing

scBS-seq is a version of the well-established bisulfite sequencing (BS-seq) and post-bisulfite adapter tagging (PBAT) protocols, modified to detect methylated cytosines in gDNA from single cells (Smallwood et al., 2014). In this method, after single cells are isolated, gDNA is treated with sodium bisulfite, which fragments the DNA. The converted DNA then undergoes random priming several times and is PCR-amplified for sequencing. Deep sequencing provides single-nucleotide resolution mapping of methylated cytosines.
