N1 - Funding Information:
We would like to thank vendors, Applied Biosystems, GE Healthcare, and Mergen for providing and running microarrays as part of this large-scale evaluation. In addition, we would like to thank Applied Biosystems for running TaqMan assays and Exiqon for supplying us with the ProbeLibrary kit as well as Roche Diagnostics for allowing us to use their 480 LightCycler. We thank Robert A. Greenes for reviewing the manuscript. W.P.K. was supported by the National Institutes of Health (NIH) EY014466 grant and by the Bioinformatics Division of the Harvard Center for Neurodegeneration and Repair. C.L.C. was supported by the Howard Hughes Medical Institute. F.L. and E.H. were supported by the functional genomics program (FUGE) in the Research council of Norway. G.M.C. was supported by NIH-NHGRI-CEGS. M.W.F., B.S. and G.F.S. were supported by Programs for Genomic Applications grants HL66678 and HL72358. R.B. was supported by NIH grants HL072370 and ES011387.

N2 - Over the last decade, gene expression microarrays have had a profound impact on biomedical research. The diversity of platforms and analytical methods available to researchers have made the comparison of data from multiple platforms challenging. In this study, we describe a framework for comparisons across platforms and laboratories. We have attempted to include nearly all the available commercial and 'in-house' platforms. Using probe sequences matched at the exon level improved consistency of measurements across the different microarray platforms compared to annotation-based matches. Generally, consistency was good for highly expressed genes, and variable for genes with lower expression values as confirmed by quantitative real-time (QRT)-PCR. Concordance of measurements was higher between laboratories on the same platform than across platforms. We demonstrate that, after stringent preprocessing, commercial arrays were more consistent than in-house arrays, and by most measures, one-dye platforms were more consistent than two-dye platforms.
