Methylation arrays enable quantitative interrogation of selected methylation sites across the genome, offering high-throughput capabilities that minimize the cost per sample. Array-based methylation studies can provide valuable insights into the regulation of gene expression. DNA methylation allows cells to suppress expression of viral and nonhost DNA elements, and facilitates response to environmental stimuli. Aberrant DNA methylation (hyper- or hypomethylation) and its impact on gene expression have been implicated in many biological processes and diseases.
Methylation microarrays combine comprehensive coverage and high-throughput capabilities. Advantages include:
The Infinium Methylation Assay allows you to interrogate CpG sites at single-nucleotide resolution, providing highly robust measurements of DNA methylation. Choose from one of our curated genome-wide arrays, or design your own microarray for targeted applications.
This array is ideal for epigenome-wide association studies (EWAS), tumor profiling, and various cell biology experiments. 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 of epigenetics research.
The Mouse Methylation BeadChip can be used in EWAS and other experiments probing the methylome in healthy and diseased tissues. Much like the MethylationEPIC BeadChip, the Mouse Methylation BeadChip offers genome-wide coverage, with probes targeted to CpG islands, enhancer regions, transcription start sites, and other important regions of the methylome.
Custom Methylation Beadchips provide the ultimate flexibility and cost-savings for targeted research and commercial applications. Custom beadchips can be designed with between 3,000 and 100,000 markers for a variety of applications. The high-throughput 24-sample beadchip reduces per sample and processing costs while maintaining the same robust methylation measurements provided by the Infinium assay.
Our methylation arrays follow a 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, these methylation microarrays offer powerful resolution for understanding epigenetic changes.
