General Information

Genome-wide association studies (GWAS) map genetic variants associated with diseases across the genome. Infinium HD BeadChips offer GWAS researchers the flexibility to profile samples in various multiplex formats, and deliver dense genome-wide coverage with carefully selected tag SNPs.

Illumina’s unique BeadArray technology is based on 3 micron silica beads that self assemble in microwells on planar silica slides. Each bead is covered with hundreds of thousands of copies of a specific oligonucleotide, which act as the capture sequence in the Infinium HD Assay protocol. Outstanding characteristics of the BeadArray technology include 100% quality control of every single array, and high feature-redundancy (>20x average) providing high-confidence results.
