  • miRNA promoter regions

Integrated Analysis Software

MethylationEPIC data analysis is supported by the GenomeStudio Methylation Module. GenomeStudio Software enables researchers to effortlessly perform differential methylation analysis for small-scale studies. It features advanced visualization tools that enable researchers to view vast amount of data in a single graph, such as heat maps, scatter plots, and line plots. 

Infinium PsychArray-24 Kit

Infinium PsychArray-24 Beadchip helps researchers to evaluate genetic variants associated with common psychiatric disorders. This cost-effective, high-density microarray was developed in collaboration with the Psychiatric Genomics Consortium for large-scale genetic studies focused on psychiatric predisposition and risk.

Content for the Infinium PsychArray-24 includes 265,000 proven tag SNPs found on the Infinium Core-24 BeadChip, 245,000 markers from the Infinium Exome-24 BeadChip, and 50,000 additional markers associated with common psychiatric disorders.

These additional SNPs include genetic variants associated with the research of common psychiatric conditions such as schizophrenia, bipolar disorder, autism spectrum disorder, attention deficit hyperactivity disorder, major depressive disorder, obsessive compulsive disorder, anorexia, and Tourette’s syndrome.

For greater flexibility, the Infinium PsychArray-24+ version of the BeadChip can be customized to include up to 60,000 additional markers.

BovineSNP50 v3 DNA Analysis BeadChip

The BovineSNP50 v3 BeadChip microarray kit contains 53,714 highly informative SNPs uniformly distributed across the entire genome of major cattle breed types, empowering applications such as genome-wide enabled selection, identification of quantitative trait loci, evaluation of genetic merit of individuals, and comparative genetic studies.

This BeadChip was developed by Illumina in collaboration with the USDA-ARS, University of Missouri, and the University of Alberta. More than 22,000 SNP probes target novel SNP loci that were discovered by Illumina sequencing of 3 pooled populations of economically important beef and dairy cattle.

Additional content is derived from publicly available sources such as the bovine reference genome, Btau, and the Bovine HapMap Consortium data set. All SNP probes have been validated in 18 common beef and dairy breeds. This product targets evenly distributed SNPs that are polymorphic across the breeds tested and provides a median spacing of 37.4 kb.

Infinium ShrimpLD-24 BeadChip

The Infinium ShrimpLD-24 v1.0 BeadChip enables genomic selection and evaluation for family identification within Pacific white shrimp (Litopenaeus vannamei), to advance aquaculture breeding programs. This microarray contains over 6400 genome-wide single nucleotide polymorphisms (SMPs), validated using family brood stock from multiple existing breeding programs.

This array offers:

  • Excellent call rates and accuracy- 99% mean call rate and > 99.9% reproducibility
  • High-value content with comprehensive coverage- Evenly distributed polymorphic SNPs with 1cM mean spacing
  • High-throughput and flexible format- Up to 24 samples can be genotyped in parallel

Infinium Global Screening Array-24 Kit

The Infinium Global Screening Array-24 v2.0 BeadChip combines multi-ethnic genome-wide content, curated clinical research variants, and quality control (QC) markers for precision medicine research.

The genome-wide content was selected for high imputation accuracy at minor allele frequencies of >1% across all 26 1000 Genomes Project populations. The clinical research content includes variants with established disease associations, relevant pharmacogenomics markers, and curated exonic content based on ClinVar, NHGRI, PharmGKB, and ExAC databases. Quality control content enables sample identification and tracking for large-scale genomics and screening applications.

Widespread Adoption

With over 5.5 million samples worth of BeadChips sold before commercial launch, the array’s global adoption provides a network of human disease researchers, healthcare networks, consumer genomics companies, and genomic service providers to help power discovery.

Broad Clinical Research Applications

The array provides a genomic tool for clinical research applications including disease risk profiling studies, pharmacogenomics research, wellness characterization, and complex disease discovery.

In March 2018, Illumina released a free update enhancing coverage in pharmacogenomics, ClinVar, HLA, and ACMG variants.
