What is the Affymetrix GeneChip® array?
The Affymetrix GeneChip® system provides an approach to comparatively analyze genome wide patterns of gene expression using a technology that incorporates miniaturized, high density arrays of 25mer oligonucleotide probes. The probe arrays are manufactured by Affymetrix’s proprietary, light directed chemical synthesis process, which generates high density arrays of oligonucleotides that possess a predefined position on the array. These arrays are used to monitor gene expression for thousands of transcripts. There are several types of Affymetrix GeneChip® arrays. Our facility primarily works with three kinds: 3′ expression arrays, Whole Transcript (Exon and Gene) arrays, and miRNA arrays.
