Comprehensive coverage for epigenome-wide association studies

Quantitatively interrogate methylation sites across the genome at single-nucleotide resolution

Methylation Array Analysis

DNA methylation plays an important and dynamic role in regulating gene expression. With the MethylationEPIC BeadChip, researchers can interrogate over 850,000 methylation sites quantitatively across the genome at single-nucleotide resolution. Multiple samples, including FFPE, can be analyzed in parallel to deliver high-throughput power while minimizing the cost per sample.

Powered by the industry-leading Infinium assay, the MethylationEPIC BeadChip is ideal for epigenome wide association studies (EWAS). It offers comprehensive, expert-selected coverage, including 99% of RefSeq genes, 95% of CpG islands, high coverage of enhancer regions, and other content categories. With >90% of the original content from the Infinium HumanMethylation450K covered, the MethylationEPIC kit supports the next generation.

The MethylationEPIC BeadChip combines comprehensive coverage and high-throughput capabilities, making it ideal for EWAS. Additional advantages include:

  • Comprehensive genome-wide coverage (> 850,000 methylation sites)
    • CpG islands
    • Non-CpG and differentially methylated sites
    • FANTOM5 enhancers
    • ENCODE open chromatin
    • ENCODE transcription factor binding sites
    • miRNA promoter regions
  • Assay reproducibility
    • 98% for technical replicates
    • 98% for the same samples on the legacy HumanMethylation450K array vs. the MethylationEPIC array
    • >90% of the HumanMethylation450K content
  • User-friendly, streamlined workflow
  • Compatible with FFPE samples
iScan

The MethylationEPIC BeadChip follows a user-friendly, streamlined workflow, enabling processing of up to 96 samples simultaneously from low sample input (as little as 250 ng).

Offering quantitative measurement at the single-CpG-site level for normal and FFPE samples, this methylation microarray offers powerful resolution for understanding epigenetic changes.
