Sample GSM127054 Query DataSets for GSM127054
Status Public on Aug 12, 2006
Title Rat liver, treated with Caerulein, 50 µg/kg in saline i.p., extrated 48 hours after treatment, biological rep1
Sample type RNA
 
Source name Rat liver, left lateral lobe
Organism Rattus norvegicus
Characteristics Male Sprague-Dawley (Crl:CD(SD)IGS Br
Age: between 5 and 6 weeks old
Biomaterial provider Scantox, Lille Skensved, Denmark
Treatment protocol The animals were sacrificed 48 hours after treatment and organs were frozen for later analysis. Tissue samples of the left lateral lobe of the liver were snap frozen in liquid nitrogen, transferred to dry ice and stored at approximately -80?C
Extracted molecule total RNA
Extraction protocol Frozen liver samples were homogenized in 2 ml TRIzol® reagent (Invitrogen ; Life Technologies, Scotland) using an Ultra Turrax T25 basic homogenizer (IKA Labortechnik; IKA-Werke, Staufen, Germany). Chloroform (400 ?l) was added and homogenized samples were shaken vigorously by hand for 15 seconds. Phase separation was achieved by centrifugation for 15 min at 10,000 × g at 4°C. Total RNA from the aqueous phase was purified using the RNeasy 96 Qiagen vacuum system following the “Clean-up” procedure.
Label biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 6 microg total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
 
Hybridization protocol Following fragmentation, 10 microg of cRNA were hybridized for 16 hr at 45C on GeneChip Rat 230 version 2 Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
Scan protocol GeneChips were scanned on GeneChip® Scanner 3000 7G 4C
Description Gene expression data from rat liver 48 hours after treatment with compound.
Data processing The data were analyzed with RMA. R was used with the affy package. Expresso with the following settings (bgcorrect.method=rma, normalize.method = quantiles.robust, pmcorrect.method=pmonly, summary.method=liwong) was used to normalize
