BeadArray Microarray

BeadArray microarray technology represents a fundamentally different approach to high-density arrays. BeadArray product density advancements have increased genomic coverage for whole-genome genotyping, resolution for cytogenetics and CNV detection, and sample throughput for gene expression, DNA methylation, and focused genotyping.

BeadArray microarray technology is utilized in Illumina array products and array scanners for a broad range of DNA and RNA analysis applications.

The HiScan and iScan systems possess the advanced laser and optics components capable of handling even the highest density multi-sample arrays, producing high-quality data with rapid turnaround times.

The Universal BeadChip format is used in Illumina's focused genotyping arrays.

The BeadChip array format is used in Illumina's Infinium Genotyping, DASL Gene Expression, and focused genotyping arrays.

The advanced Infinium HD assay delivers high data quality with an average call rate of 99.9%. These high sample call rates make downstream curation of data easy and decrease the likelihood of false positives and negatives.
