Randomized trial demonstrates scalable analysis of DNA methylation across tissues, indicating significant variations in methylation states.

This research aims to enhance the analysis of genome-wide DNA methylation using the Infinium assay.
Applied Infinium genotyping technology to analyze bisulfite-converted DNA.
Measured methylation levels across 14 human tissues and multiple cancer cell lines.
Utilized modified Zymo EZ DNA Methylation kit for bisulfite conversion.
Approximately 80% of CpG sites in CpG islands were unmethylated (β < 0.2).
Only 12% of CpG sites in non-CG islands were unmethylated (β < 0.2).
Tissue-specific methylation variation was more prevalent in non-CG islands compared to CG islands.

Bibikova et al. (2009) studied this question.
