Affymetrix GeneChip ArraysGeneChip Array Overview The GeneChip high-density oligonucleotide arrays are fabricated by using in-situ synthesis of short oligonucleotide sequences on a small glass chip using light directed synthesis. This technique allows for the precise construction of a highly ordered matrix of DNA oligomers on the chip. Traditionally, Affymetrix GeneChip Arrays are manufactured as a single array caged in a
