Sample GSM932850 Query DataSets for GSM932850
Status Public on Mar 22, 2013
Title Control sham-operated cortex Replicate 4
Sample type RNA
 
Channel 1
Source name Control sham-operated cortex Pool
Organism Rattus norvegicus
Characteristics treatment: sham
tissue: Brain - cortex
strain: Sprague Dawley
Growth protocol Brain tissues were collected from 4 transient middle cerebral artery occlusion (tMCAO) rats and 4 controls at 24 hr. Selection of optimal time points was primarily based upon the time course of infarct formation (histological data). Brain tissue of 4 mm thick ipsilateral brain section (dissected into cortex and striatum) were collected but only cortex samples were used for expression profiling.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from brain cortex using Qiagen RNeasy Midi kit as described by the manufacturer. Samples were treated with DNaseI on-column (Qiagen) for 30 minutes. RNA concentration was measured using a NanoDrop ND-1000 and RNA integrity was determined with a 2100 Bioanalyzer.
Label Cy3
Label protocol 100 ng-input two-round RT/IVT RNA amplification protocol

Label Cy5
Label protocol 100 ng-input two-round RT/IVT RNA amplification protocol
 
 
Hybridization protocol Oligoarray control targets and hybridization buffer (Agilent In Situ Hybridization Kit Plus) were added, and samples were applied to microarrays enclosed in Agilent SureHyb-enabled hybridization chambers. After hybridization, slides were washed sequential
Scan protocol Scanned on an Agilent G2565AA scanner.
Images were quantified using Agilent Feature Extraction Software (version A.8.5.1.1).
Description Biological replicate 4 of 4 sham-operated cortex
Data processing Agilent Feature Extraction Software (v 8.5.1.1) was used for background subtraction and LOWESS normalization.
