Illumina iScan System


The Illumina iScan system is an array scanner that supports sensitive and accurate imaging of Illumina’s array based genetic analysis products.


Illumina bead-based microarray technology uses silica microbeads. As DNA fragments pass over the BeadChip, each probe binds to a complementary sequence in the sample DNA, stopping one base before the locus of interest. Allele specificity is conferred by a single base extension that incorporates one of four labeled nucleotides. When excited by a laser, the nucleotide label emits a signal. The intensity of that signal conveys information about the allelic ratio at that locus.
