Illumina microarray solutions

Screening tools for analyzing genetic variation on any scale

Microarrays and Array Techniques

From discovery applications to routine screening, microarrays are a valuable tool for variant detection. Powered by widely adopted Infinium technology, Illumina microarrays provide the trusted data quality needed to accelerate research. The scalable, multi-sample format supports labs conducting large studies or institutions processing high sample volumes, making it easier to keep pace with demand.

As genomic information becomes incorporated into precision medicine initiatives, clinical and translational research, pharmacology, consumer screening, and agricultural applications, we're continuing to develop microarrays to meet diverse research needs. Whether you're running a few or thousands of samples per day, our arrays can help you analyze genetic variation efficiently.

Dr. Weiss discusses how Illumina microarrays offer the quality and accuracy needed for disease research.

Microarrays are ideal for surveying thousands of samples to identify point mutations, structural variants, or changes in gene expression and methylation. Illumina microarrays offer several advantages.

  • Trusted data quality
  • Widespread global adoption, fostering collaboration and accelerating research
  • Detection of chromosomal alterations and copy number variation (CNV)
  • Scalable workflow for large studies, including population-scale genotyping
  • Integration with Illumina sequencing systems for multi-omics analyses
  • Flexible content
  • Built-in lab management, tracking, and traceability tools
Benefits of Microarrays
Human Genotyping

Perform whole-genome or targeted genotyping of human samples for precision medicine research, pharmacogenomics, translational research, consumer screening applications, and disease association studies. Tailor studies to detect common variants, CNVs, and more.

Non-Human Genotyping

Conduct whole-genome selection studies, DNA fingerprinting, net merit evaluation, and marker-assisted breeding with species-specific catalog and consortia-developed microarrays, or genotype species of interest with custom arrays.

Methylation Analysis

Analyze epigenetic patterns across the genome with methylation arrays. Quantify changes to CpG islands, non-CpG and differentially methylated sites, and regulatory regions with single-nucleotide resolution.

Learn More
Genome-Wide Genotyping

Microarray-based genome-wide association studies (GWAS) have been the most common approach for identifying disease associations across the whole genome.

Learn More
Targeted Genotyping

Targeted genotyping approaches provide a cost-effective alternative to whole-genome methods, when genome-wide genotyping is not practical or necessary.

Custom Genotyping

Custom genotyping is the ideal solution for screening large sample sets against novel or targeted content. With custom designs, you can target regions of the genome relevant to your specific research interests.
