Sample GSM153539 Query DataSets for GSM153539
Status Public on Dec 26, 2007
Title LT 342 +/T untreated
Sample type RNA
 
Source name Alpha7 nAChR subunit L250T heterozygous mice without treatment
Organism Mus musculus
Characteristics Strain: C57BL/6J
Gender: M
Age: 6 weeks
Treatment: untreated
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from whole brains using TRI REAGENT (Sigma-Aldrich, St. Louis, MO) according to the manufacturer’s instructions, and further purified on a Qiagen RNeasy mini kit (Qiagen Sciences, Germantown, MD)
Label biotin-labeled
Label protocol 10 mg of total RNA were used to synthesize double-stranded cDNA with the Superscript Choice System (Invitrogen, Carlsbad, CA) and 100 pmole of oligo-dT primer attached to a T7 promoter sequence (Genset, Paris, France). The double-stranded cDNAs were phenol/chloroform extracted with Phase Lock Gels tubes (Eppendorf, Hamburg, Germany). In vitro transcription (IVT) of the double-stranded cDNA products was performed with an Enzo BioArray High Yield Transcript labeling kit in the presence of biotin-labeled nucleotides (Affymetrix, Inc., Santa Clara, CA). Following purification by an RNeasy mini kit (Qiagen Sciences), the biotin-labeled cRNA products were subjected to alkaline lysis (200mM Tris-acetate pH 8.1, 500mM potassium acetate, 150mM magnesium acetate).
 
Hybridization protocol Fragmented cRNAs were hybridized overnight at 45°C to Affymetrix Gene Chip Murine Genome U74Avr2 arrays (Affymetrix, Inc.).
Scan protocol Affymetrix Gene-Array Scanner
Description Total RNA was extracted from whole brain. Total RNA isolation, target preprocessing and hybridization to the U74Av2 microarray were conducted according to Affymetrix’s instructions.
Data processing The signal values were generated by statistical algorithm implanted in Affymetrix Suite Version 5.0 software (MAS5, Affymetrix, Inc.) The detection calls were calculated, based on the detection p-value, as following: probe sets with p-value of more than 0.06 were designated as absent, p-value of more than 0.04 and less than 0.06 as marginal and p-value of less than 0.04 as present. For interarray comparisons, data from each array was scaled using MAS5 software, and the mean intensity for each array was adjusted by a scaling factor to a set target intensity of 150.
