Dataset link Gene expresssion changes in pancreatic islets of 11 weeks old IKK2-CApdx-1 mice compared to control and Pdx-1+/- mice

Experimental Protocol


Pancreatic islets were isolated from 11 weeks old control (n=5), Pdx-1+/- (n=4) and IKK2-CApdx-1 (n=5) mice, total RNA was extracted with RNeasy mini kit (QIAGEN). Microarray analyses were performed using 200 ng total RNA as starting material and 5.5 µg ssDNA per hybridization (GeneChip Fluidics Station 450; Affymetrix, Santa Clara, CA). The total RNAs were amplified and labeled following the Whole Transcript (WT) Sense Target Labeling Assay (http://www.affymetrix.com). Labeled ssDNA was hybridized to Mouse Gene 1.0 ST Affymetrix GeneChip arrays (Affymetrix, Santa Clara, CA). The chips were scanned with a Affymetrix GeneChip Scanner 3000 and subsequent images analyzed using Affymetrix® Expression Console Software (Affymetrix). Probe level data were obtained using the robust multichip average (RMA) normalization algorithm.
