FIGURE 3.7: The Illumina Golden Gate assay. The GoldenGate assay is
based on the BeadArray technology: as say oligonucleotides, containing an ad-
dress sequenc e , hybridize to gDNA to identify the allele at a given loci. After
processing and amplification, the amplified product binds to a bead on the ar-
ray that contains a complementary address sequence. Dual-color fluorescence
dyes, specific to e ach ASO, indicate the g enotype of the SNP from the gDNA
fragment. Courtesy o f Illumina, Inc.
