|
| Treatment protocol |
No additional treatment was used prior to RNA extraction
|
| Growth protocol |
anti-TNFa siRNA treatment in a mouse model of IBD: effects of various chemical modifications on clinical parameters and the inflammatory axis.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was prepared using a RNEasy RNA extraction kit (Qiagen). Purity and integrity of the purified RNA was assessed on the Agilent Bioanalyzer 2100. Concentration was determined with a Nanodrop ND-1000 Spectrophotometer.
|
| Label |
biotin
|
| Label protocol |
25 ng total RNA per sample was used for Whole Transcriptome Amplification (Sigma) according to manufacturer´s recommendations. 10 microgram cDNA was fragmented, and biotinylated using Affymetrix' 10K v2 Assay Kit according to manufacturer's recommendations (http://www.affymetrix.com).
|
| |
|
| Hybridization protocol |
Hybridization of the samples to Affymetrix GeneChip® Mouse Gene 1.0 ST Arrays were performed according to the manufacturer’s instructions (http://www.affymetrix.com).
|
| Scan protocol |
GeneChips were scanned using the Affymetrix GeneChip@ Scanner 3000.
|
| Description |
The U of U/miligramsg stands for Unit of MPO activity. One unit of MPO activity was defined as the amount that degraded 1.0 umol of peroxide per min at 25 C.
|
| Data processing |
Gene expression data was pre-processed and normalized using Partek Genomics Suite. The data was quantile normalized, and the summarization was obtained via RMA.
