The Infinium MethylationEPIC Array is a genome-wide DNA methylation analysis technique based on bisulfite conversion and Illumina® technology. It allows to quantitatively detect the total methylation level of over 850,000 methylations sites throughout the human genome at single nucleotide resolution. It offers comprehensive, expert-selected coverage of CpG islands, enhancer regions, open chromatin sites and other important regions of the methylome.

Briefly, upon bisulfite treatment, unmethylated cytosines (both 5mC and 5hmC) are converted to uracils, while methylated cytosines remain unchanged. Infinium HD array technology interrogates these differentiated loci using site-specific probes (designed for the methylated and unmethylated sites respectively). The level of total methylation for the interrogated locus can be determined by calculating the ratio of the fluorescent signals from the methylated vs. unmethylated sites.

    Standard files provided:

    • Sample annotation
    • Variable annotation
    • Raw data (un-normalized β values and detection p-values)
    • Scanner output

    Differential methylation analysis

    Identification of differentially methylated CpGs between sample groups.

    Files provided:

    • Report with summary of differential methylation analysis and plots
    • File containing the differentially methylated CpGs and breakdown of those positions in regional analysis (CpG islands, shelves, shores and open sea)
    • File containing differential methylated regions (DMRs)

    Gene ontology terms analysis

    Enrichment analysis on gene sets. Gene Ontology terms that are overrepresented in differentially bound regions may indicate the underlying biological processes involved.

    Pathway analysis

    Identify biochemical pathways in which genes associated with differentially methylated regions (or individual differentially methylated CpGs) may be overrepresented.
