The array uses both Infinium I and Infinium II assays. Infinium I assay design employs two bead types per CpG locus, one each for the methylated and unmethylated states. The Infinium II design uses one bead type, with the methylated state determined at the single base extension step after hybridization.
GenomeStudio Software supports DNA methylation analysis on any platform. Data are displayed in intuitive graphics (heatmap).
