Custom design tools for genotyping any variant, in any species

Custom Genotyping

Custom genotyping is the ideal solution for screening large sample sets against novel or targeted content. With custom designs, researchers can target regions of the genome relevant to their specific research interests. Illumina offers flexible options and simple online design tools to maximize success with your customized genotyping assays.

  • Enable studies of species or populations not supported by standard products
  • Allow researchers to focus on genes, variants, and/or genomic regions of interest relevant to certain diseases or traits of interest, but not covered in pre-designed products
  • Conserve resources by avoiding irrelevant regions of the genome
Fully custom arrays

Custom genotyping arrays can be developed easily with up to 700,000 markers targeting any loci across the genome, for any species, including novel organisms. Illumina also offers flexible throughput options, including robotic automation capabilities for high-throughput custom genotyping projects.

Custom add-on content

This option allow researchers to add new custom content to Custom iSelect, Infinium array products, or consortia-developed products. Scientists can combine existing marker sets with new, unique content on a single microarray. The amount of add-on content supported depends on the base content and associated BeadChip array and will vary for each product.
