Comment[ArrayExpressAccession] E-GEOD-41328 MAGE-TAB Version 1.1 Public Release Date 2012-10-03 Investigation Title Colorectal adenocaricinomas and matched normal colonic tissues Comment[Submitted Name] Colorectal adenocaricinomas and matched normal colonic tissues Experiment Description Five colorectal adenocarcinomas and matched normal colonic tissues were analyzed with Affymetrix HG-U133-Plus-2.0 microarrays. Two labs independently generated microarray data with the same array platform on the same biological samples. Colorectal adenocarcinomas and matched normal colonic RNA sample were purchased from Oncomatrix, Inc., San Diego, CA. The RNA from each biological sample was distributed to and processed in two laboratories at Stanford University.

The microarrays were hybridized for 16 hours at 45°C, stained, and washed according to an Affymetrix protocol (EukGE-WS2v4) using an Affymetrix fluidics station. Colorectal adenocarcinomas and matched normal colonic RNA sample were purchased from Oncomatrix, Inc., San Diego, CA. 5 µg of total RNA was used to synthesize cRNA for each sample. The CEL file data were analyzed with BioConductor to generate probeset level data using the justPlier() function. Probe-level data were quantile normalized before PLIER summarization per test site (10 arrays). An offset value of 16 was then added to each probeset-level data point.
