Principle and Workflow of Whole Genome Bisulfite Sequencing - CD Genomics

Epigenetic studies have confirmed that DNA-methylation modification of specific gene regions plays an important role in chromosome conformation and gene expression regulation. Methylation of DNA cytosine residues at the C5 (5meC) is a common epigenetic mark in many eukaryotes and is widely found in CpG or CpHpG (H=A, T, C). There are mainly three approaches, including endonuclease digestion, affinity enrichment, and bisulfite conversion (Table 1). Almost all sequence-specific DNA methylation analysis approaches require a methylation-dependent treatment before amplification or hybridization to maintain fidelity. Various molecular biology techniques, such as next-generation sequencing (NGS), are subsequently performed to detect 5meC residues. https://www.cd-genomics.com/principles-and-workflow-of-whole-genome-bisulfite-sequencing.html
