(Submitter supplied) Microarray technology has had a profound impact on gene expression research. Some studies have questioned whether similar expression results are obtained when the same RNA samples are analyzed on different platforms. The MicroArray Quality Control (MAQC) project was initiated to address these concerns, as well as other performance and analysis issues. We demonstrate the consistency of results within a platform across test sites as well as the high level of cross-platform concordance in terms of genes identified as differentially expressed. more...

(Submitter supplied) Well-annotated mRNA or coding sequences were chosen to ensure usefulness for a large range of applications in basic research, biotechnology, and drug development. Each sequence was carefully screened to ensure high-quality, specific probe design, and to reduce redundancy of gene targets. All of the probes designed to these sequences were functionally tested, and over 95% were functionally validated against 10 rat tissues to ensure best representation of the gene and biologically relevant results. more...
