How can DNA methylation as an epigenetic modification be measured?

Here is an answer generated by AI:

DNA methylation, an epigenetic modification, can be measured using several methods:

• Chromatin Immunoprecipitation (ChIP): This method uses methylation-specific antibodies to purify methylated regions of the genome. The DNA is then analyzed by microarray or Next Generation Sequencing (NGS) to identify these regions.
• Bisulfite-based methods: These involve treating the DNA sample with bisulfite, which converts unmethylated cytosine bases to a uracil base, while leaving methylated residues as a cytosine. The treated DNA is then analyzed by microarray or NGS.
• Restriction enzyme-based DNA methylation analysis: This includes various methods like MS-AFLP, DMH, CHARM, MMASS, HELP, MS-MLPA, LUMA, RLGS, and MCA.

Each method has its own advantages and is used based on the specific requirements of the study.
