Overview
The Infinium Custom Methylation Kit contains the Infinium HTS iSelect Methyl Custom BeadChip plus reagents to enable researchers and commercial users to develop groundbreaking assays for critical epigenetic research applications.
High-throughput workflow
The Infinium HTS iSelect Methyl Custom BeadChip is offered in a 24-sample format with updated Infinium automation protocols and an automated workflow for bisulfite conversion. These features improve workflow efficiency, decrease sample processing costs, and allow users to scale their operations up to hundreds of thousands of samples per year.
Customizable content
Customize arrays with up to 100K additional markers to create unique research tools. Select content from existing commercial arrays or epigenetic databases.
Proven Infinium chemistry
The Infinium BeadChip design enables a high degree of methylation probe replication, resulting in high reproducibility, comparable to 100× coverage in methylation sequencing experiments. 1
Key features of the Infinium Custom Methylation Kit
Customizable content supports up to 100K markers
Accurate quantitative measurement of DNA methylation at the single-CpG-level
Rapid turnaround time with optional automated bisulfite conversion
Applications
The Infinium Custom Methylation Kit allows users to create custom high-throughput assays to measure DNA methylation in targeted regions of the genome for academic epigenetic applications, including common disease research, cancer research, epigenetic aging, and nutriepigenomics.
Example workflow
Methylation arrays
Methylation arrays enable high-throughput, quantitative interrogation of methylation sites across the genome at single-nucleotide resolution.
iScan System
The iScan microarray scanner supports high-throughput BeadChip processing, scanning hundreds to thousands of samples quickly and accurately.
GenomeStudio software
GenomeStudio software provides an integrated platform for data analysis of microarray-based genotyping assays, with a user-friendly graphical interface.
Related applications and methods
Epigenetics
Illumina offers solutions for epigenetic analysis. Use our tools to study epigenetic modifications and their impact on gene regulation.
DNA methylation analysis
Genome-wide methylation profiling studies with microarray and NGS technologies can provide novel insights into the functional impact of methylation.
High-throughput genotyping
Large-scale genotyping with microarrays can identify variants associated with disease risk in large cohorts or populations.
Infinium I and II assays allow for broader coverage of CpG sites
Illumina methylation BeadChips employ both Infinium I and Infinium II assays, enhancing the overall breadth of coverage. (A) Infinium I probe designs use 2 bead types per CpG locus, 1 each for the methylated and unmethylated states. (B) Infinium II probe designs use 1 bead type for both states.
Design and manufacturing process
Researchers work with Illumina technical design and customer service teams to refine the BeadChip marker content and coordinate the ordering and production process.

How do I analyze the Infinium HTS iSelect Methyl Custom BeadChip data?
For methylation QC, GenomeStudio 2011, Methylation Module, or DRAGEN Array Methyl QC can be used for human species.
For downstream methylation analysis or analysis of non-human species, SeSAMe ( https://www.bioconductor.org/packages/release/bioc/html/sesame.html ) or other third party bioconductor tools are recommended at this time.
Which bisulfite conversion kit should I use?
The Zymo Research EZ-96 Methylation-Lightning MagPrep Kit in manual and automated formats is supported for use upstream to Infinium Methylation assays. Review results in this technical note for more details.
