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
