For researchers who want to study focused genomic regions of interest, or are interested in organisms for which there are no standard products, Illumina offers a broad range of custom genotyping options. Customized iSelect BeadChips can be easily developed to fit any experimental design, allowing customers to select the ideal solution for their loci multiplexing and sample throughput requirements. Convenient online tools and Illumina representatives are available to help you design and select your markers of interest, and choose the assay and customized products to best suit your research goals.


iSelect HD Custom Genotyping

The iSelect HD Custom Genotyping program enables easy, versatile design of custom arrays to investigate markers targeting:

  • Any species, with the flexibility of assaying virtually any marker in the genome
  • Disease or pathway specific markers
  • Rare variants, CNVs, and much more

Illumina's fully custom genotyping platform offers all of the benefits of standard Infinium products, including industry-leading data quality and call rates, streamlined workflow, and rational SNP selection with access to the entire genome of any species.

iSelect HD Custom BeadChips

Access the enhanced multiplexing capabilities of the Infinium HD Assay on the 24-sample (3,000 to 90,000 attempted bead types), 12-sample (90,000 to 250,000 attempted bead types), or the 4-sample (250,000 to 1,000,000 attempted bead types) format BeadChips.

Semi-Custom Infinium HD BeadChips

For array customization in human studies, add up to 200,000 markers to the standard whole-genome SNP genotyping content of the Human OmniExpress+ BeadChip.
