(Submitter supplied) Gene expression profiling is an important tool in the development of medical countermeasures against chemical warfare agents (CWAs). Non-human primates (NHPs), specifically the rhesus macaque (Macaca mulatta), the cynomologus macaque (Macaca fascicularis) and the African green monkey (Chlorocebus aethiops), are vital models in the development of CWA prophylactics, therapeutics, and diagnostics. However, gene expression profiling of these NHPs is complicated by the fact their genomes are not completely sequenced, and that no commercially available oligonucleotide microarrays (genechips) exist. more...

(Submitter supplied) The yeast 5803 ORFs MicroArray is composed of 32 subgrids, which follow a pattern of 8 metarows and 4 metacolumns. Each subgrid contains 20 columns and 20 rows with a dot spacing of 200 µm. Probes are spotted as closed duplicates. In order to provide a friendly environment, the first subgrid row on each array metarow contains all the normalization controls, which include the controls with serial dilution of the Renilla LuxA cDNA PCR product. more...

(Submitter supplied) We present a novel method of using commercial oligonucleotide expression microarrays for aCGH, enabling DNA copy number measurements and expression profiles to be combined using the same platform. This method yields aCGH data from genomic DNA without complexity reduction at a median resolution of approximately 17,500 base pairs. Due to the well-defined nature of oligonucleotide probes, DNA amplification and deletion can be defined at the level of individual genes and can easily be combined with gene expression data. more...

(Submitter supplied) The publicly available genome sequence information of two rice strains, japonica cultivar Nipponbare and indica cultivar 93-11, opens a great opportunity for investigation of performances DNA genotyping by high-density oligonucleotide arrays. Here, we compare single feature polymorphism (SFP) detection performances between whole genome hybridization and transcript hybridization using Affymetrix Rice Expression Array and the two rice cultivars.

(Submitter supplied) The Arabidopsis Pathoarray 464_001 (GPL3638) was used to compare response of wild-type, rps2-101C (Bent et al., 1994; Mindorinos et al., 1994) and ndr1-1 (Century et al., 1995) to Pseudomonas syringae strain expressing avrRpt2. The two mutants are compromised in RPS2-mediated resistance but distinct difference between them has not been described. The results suggested that ndr1-1 affects a defense signaling pathway(s) in addition to the RPS2-dependent pathway, and indicate that the microarray is a powerful tool for systems analysis of the Arabidopsis disease signaling network. more...

(Submitter supplied) In order to protect themselves from pathogens, plants activate a battery of defense pathways, many of which involve changes in gene expression. We are interested in identifying plant genes that are differentially expressed in response to pathogen exposure, with the ultimate goal of studying the roles of these genes in plant defense.

(Submitter supplied) To assist in the identification of proteases, their endogenous inhibitors, and proteins that interact with proteases or proteolytic pathways in biological tissues, a dual species oligonucleotide microarray has been developed in conjunction with Affymetrix, Inc. To investigate the performance of the array, gene expression profiles were analyzed in pure mouse and human samples and orthotopically implanted xenografts of human A549 lung and MDA-MB-231 breast carcinomas. more...
