Genotyping microarrays, also known as SNP arrays, enable the parallel analysis of hundreds of thousands to millions of single-nucleotide polymorphisms (SNPs) across the genome. As a high-throughput and cost-effective platform, these arrays are widely used in genome-wide association studies (GWAS), trait mapping, population genetics, and other applications.
At the UMGC, we use Illumina’s Infinium technology to support both human and non-human genotyping projects, including those involving plants and animals. We process standard, consortium-based, and fully customized array content to meet a wide range of research needs. As a high-capacity facility, the UMGC is equipped to process tens of thousands of samples with speed, affordability, and reproducibility.
Advantages of Genotyping Arrays
Genotyping microarrays combine comprehensive coverage and high-throughput capabilities. Advantages include:
- Comprehensive genome-wide coverage with high resolution, enabling detection of copy number variation (CNV), loss of heterozygosity (LOH), and insertions/deletions
- Assay reproducibility
- Cost-effective and scalable
Illumina Genotyping Microarrays
Human Genotyping Arrays
Features expert-selected content, including established consortium markers and customizable options tailored to specific research goals. These arrays are well-suited for large-scale population studies, clinical research, and genetic screening.
Non-Human Genotyping Arrays
For non-human organisms, such as crops, livestock, and model species, Illumina provides ready-to-use and custom iSelect arrays. These arrays offer high-density coverage for breeding, trait selection, and disease susceptibility.
Custom and Pre-Designed Arrays
Custom genotyping arrays offer flexible, high-throughput solutions with up to 700,000 markers for any species, including novel organisms. Researchers can work with Illumina to design fully custom arrays or add new content to existing arrays.
To find the array best suited to your research, we recommend using Illumina’s Array Kit Selector.

Notes
1. Pricing for a genotyping microarray project has two components: 1) the Illumina microarray kit and reagents (inquire), and 2) the cost of microarray processing (listed above).
2. Tiers: Turnaround time (TAT) is in business days. TAT is for sequencing only and does not factor in the TAT for library prep or other companion services. Availability for the Priority Tier is limited; contact [email protected] to see if this is a current option. More information about Pricing Tiers.
