Sample GSM790931 Query DataSets for GSM790931
Status Public on Sep 10, 2011
Title TNFa-OMe siRNA-B, replicate 3
Sample type RNA
 
Source name TNFa-OMe siRNA-B, replicate 3
Organism Mus musculus
Characteristics knockdown: TNFa-OMe siRNA-B
amplification date: 09/06/19
hybridization date: 09/06/30
colon length (mm): 6
colon weight (mg): 172
colon ratio (mg/mm): 2.87
myeloperoxidase activity (u/mg): 0.384
tissue: colon
treatment: 5% DSS
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.
