Affymetrix has added a number of arrays to its catalog, including an Arabidopsis ATH1 array containing 22,500 probe sets that represent about 24,000 genes, an E. coli antisense array covering more than 4,200 known open reading frames, a P. aeruginosa array representing the annotated genome of strain PA01, and a C. elegans array including 22,500 transcripts.

GeneMachines of San Carlos, Calif., has published an application note detailing the production of oligonucleotide microarrays by printing 50-mers onto OmniGrid Alehyde slides. The publication is available from the company on request.

London-based Inpharmatica has launched Biotech Biopendium, a proteome annotation resource with applications in microarray analysis. Companies have to license the technology for a minimum of two years but do not need to buy and run a server and Oracle license because of a hosted model. Individual research tools are available; modules include microarray high-throughput annotation processing, an open schema, proprietary data integration to the Biopendium, and GT Interactiv to provide functional annotation for novel sequences.
