The NIH Neuroscience Microarray Consortium (arrayconsortium.tgen.org) added high-density genotyping on both the Affymetrix (www.affymetrix.com) and Illumina (www.illumina.com) platforms to its list of services. Each of the four members of the Consortium—Duke Unviersity, TGen, UCLA, and Yale—offer specialized services. TGen and UCLA will offer the new Affymetrix genotyping service, while Yale will offer the new Illumina expression and genotyping capabilities.
