The new GeneChip Arabidopsis array is based on information from the international Arabidopsis sequencing project. Under a cooperative agreement with the National Science Foundation, TIGR led the effort to re-annotate the Arabidopsis genome, which resulted in the collaboration with Affymetrix on the new array design. The new array takes advantage of Affymetrix' advanced design methods to allow representation of approximately three times more information on a single array than Affymetrix' previous Arabidopsis product, introduced in 2000. "TIGR's extensive work with the Arabidopsis genome made them an excellent collaborator in the design of this new array," said Alan Dance, Sr. Vice President, Corporate Marketing, at Affymetrix. "The substantial improvements TIGR made over the past year in Arabidopsis genome annotation are incorporated into this new array and will give scientists a powerful tool for a wide variety of plant studies." "Our collaboration with Affymetrix has been very successful and this new microarray will help scientists get the robust and reproducible Arabidopsis genome data they need," said Chris Town, Ph.D., a lead scientist in TIGR's Arabidopsis project. Arabidopsis annotation data from the TIGR database will be hosted on the NetAffx(TM) Analysis Center at www.affymetrix.com and the TIGR website at www.tigr.org. The GeneChip Arabidopsis array is now available to Affymetrix customers as a Made-to-Order product. Made-to-Order arrays are shipped approximately four weeks from the order date.<< snip Cheers, Tuck
