Affymetrix last week announced the December availability of expression arrays for dog, zebrafish, and Xenopus laevis, as well as two other arrays. The GeneChip-brand Canine Genome Array is a new research tool for the study of Canis familiaris. The sequences for this array are drawn from the Lion Biosciences sequence database, and will be made available to all purchasers of the array at no additional cost, the company said in a marketing e-mail. The canine array was designed using Affymetrix’ new high-density, 11-micron format. The GeneChip-brand Zebrafish Genome Array, designed in consultation with a public consortium of zebrafish researchers, contains probe sets to over 13,000 sequences, the company said. The Xenopus laevis Genome Array, the first comercially available Xenopus whole genome array, a joint effort with a group of Xenopus researchers, will include probe sets for over 11,000 sequences.
The three new arrays will be available in lots as small as five arrays. Prices were not disclosed.
Additionally, the company announced the availability of a product contain comprehensive coverage of two organisms — Plasmodium and Anopheles — on a single array. The GeneChip Plasmod-ium/Anopheles Genome array will contain probe sets to the complete sequences of the malaria parasite, Plasmodium falciparum, with over 5,000 transcripts; and 15,000 transcripts for the host mosquito, Anopheles gambiae. The company is also releasing an array for the human pathogen, Staphylococcus aureus, which was designed in collaboration with Pfizer. The S.aureus Genome Array features probe sets to sequences from the following strains of Staphylococcus aureus: N315 (National Institute of Technology and Evaluation, Japan), Mu50 (NITE), NCTC 8325 (OU, lab strain), and COL (TIGR). The array includes over 3,300 probe sets to open reading frames (ORFs).
