The Infinium MethylationEPIC v2.0 BeadChip offers a comprehensive genome-wide discovery tool with ~930K CpG sites covering >99% RefSeq genes with promoter and enhancer-focused content. The Infinium MethylationEPIC v2.0 BeadChip is ideal for projects in which methylation profiling across all genes and promoter regions is desired for maximum discovery power. It is also ideal for all oncology applications due to its coverage of critical oncogenes, compatibility with FFPE tissue, and copy number variation profiling capabilities.
The Infinium Methylation Screening Array offers a more cost-effective methylation screening tool for the study of common disease for population health projects. The ~270K methylation sites are focused on known trait associations from epigenome-wide association studies over the past decade, as well as novel content covering cell-type specific methylation, intermediate methylation, CoRSIVs, SNPs, and more. The Infinium Methylation Screening Array is ideal for large-scale epigenome-wide association studies (EWAS) and biobank screening projects.
A comprehensive product comparison table can be found on the Infinium Methylation Screening Array datasheet.
Yes, the Methylation Screening Array requires the EX Methylation workflow while the EPICv2.0 uses HD Methylation workflow. EX Methylation delivers new sample processing efficiencies enabled by the 48 sample EX BeadChip and automation., and has a lower DNA input of 50ng. The EX Methylation workflow requires the Infinium Automated Pipetting System with ILASS for automated liquid handling.
While the Illumina product manifest file provides basic genomic mapping annotations, the Zhou Lab Infinium Annotations GitHub page provides detailed annotations including trait associations covered on the Infinium Methylation Screening Array.
The Infinium Methylation Screening Array is not recommended for oncology applications due to the following reasons:
· FFPE compatibility unvalidated
· Does not have sufficient coverage of probes for widely-used cancer classifiers
· Does not cover MGMT promoter methylation
· Limited ability to profile copy number variations
· Larger minimum batch size of 48 samples per BeadChip may result in longer turnaround times for results
Illumina offers user friendly tools to analyze Infinium controls built into the Methylation Screening Array. For more information visit the Methylation Array Data Analysis Tips page.
Yes, service labs can use the GenomeStudio Methylation Module Controls Dashboard for assessing assay performance. For downstream methylation analysis, Bioconductor packages such as SeSAMe are recommended.
The scan takes ~20 minutes per BeadChip.
Advanced chemistry, optics, and informatics combine to deliver exceptional speed and data quality, outstanding throughput and scalability.
