Illumina's BeadArray Technology is based on 3-micron silica beads that self assemble in microwells on either of two substrates: fiber optic bundles or planar silica slides. When randomly assembled on one of these two substrates, the beads have a uniform spacing of ~5.7 microns. Each bead is covered with hundreds of thousands of copies of a specific oligonucleotide that act as the capture sequences in one of Illumina's assays.
The Direct Hybridization Assay offers the highest level of multiplexing for whole-genome expression profiling available. With the most up-to-date expression content and high-throughput processing, Illumina's whole-genome expression arrays produce high-quality data for large gene expression studies, efficiently and economically.
The HumanHT-12 v4 Expression BeadChip is Illumina's latest whole-genome expression array, providing coverage for more then 47,000 transcripts and known splice variants across the human transcriptome.
