Study Demonstrates Gene Expression Microarrays are Comparable and Reproducible

ion. “This study indicates that microarrays have a high degree of reproducibility, as long as standardized protocols are carefully followed,?said Jacobson. These promising results will allow this same research group to proceed with a larger gene expression analysis of 600 stage I lung adenocarcinomas, with the hopes of confirming a previous association between gene expression profiles and patient outcome. This project is also an example of NCI interest in developing public/private partnerships. Affymetrix, of Santa Clara, Calif., contributed part of the arrays for this comparison study and provided technical assistance to the four sites carrying out the study. Ardais Corporation, Lexington, Mass., provided the RNA samples used for analysis.
