Quantitative Gene Expression Profiling in Formalin-Fixed Paraffin-Embedded Samples by Affymetrix Microarrays

(Submitter supplied) Background: To date, few studies have systematically characterized microarray gene expression signal performance with degraded RNA from formalin-fixed paraffin-embedded (FFPE) specimens in comparison to intact RNA from unfixed fresh-frozen (FF) specimens. Methodology: RNA was extracted and isolated from paired tumor and normal samples from both FFPE and FF kidney, lung and colon tissue specimens. Microarray signal dynamics on both the raw probe and probeset level were evaluated. more...
