 Introduction
|
|
Epigenome sequencing confirms that the function of a certain gene is expressed by external environmental factors. Methylation of DNA and acetylation of histone protein are the most representative epigenetic control mechanisms for the transcription of genes. They can be analyzed more effectively with NGS technology.

Whole Genome Bisulfite Sequencing
|
|
Whole Genome Bisulfite Sequencing (WGBS) is a method of observing the degree of DNA methylation by treating DNA using sodium bisulfate, which converts non-methylated cytosine to uracil, and analyzing the sequence.
|
|
|
|
Methyl-capture Sequencing
|
|
Methyl-Capture Sequencing is a method that captures the parts of the CpG where methylation was
|
|
|
previously reported and analyzes the sequence converted to sodium sulfite to observe the methylation degree.
