Sample GSM308543 Query DataSets for GSM308543
Status Public on Nov 01, 2008
Title Hippocampus veh 2
Sample type RNA
 
Source name hippocampus 24h after PBS injection
Organism Mus musculus
Characteristics Strain: C57BL/6 and SV129/Ola cross, Age: 12-15 weeks of age
Treatment protocol At sacrifice, hippocampus and cerebral cortex were rapidly dissected, flash frozen at -60°C, and stored at -80°C until RNA extraction.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from hippocampus and cerebral cortex samples using Qiagen RNeasy Lipid Tissue Mini and Midi kits, respectively (Qiagen, Valencia, CA, USA).
Label Cy3
Label protocol A 0.5 ug aliquot of total RNA from each sample was labeled using the Illumina TotalPrep RNA Amplification Kit (Ambion; Austin, TX, USA). RNA was first converted into single-stranded cDNA using reverse transcription with an oligo-dT primer containing the T7 RNA polymerase promoter, and then the single-stranded cDNA was copied to produce double-stranded cDNA molecules. The double-stranded cDNA was used in an overnight in vitro transcription reaction where single-stranded RNA (cRNA) was generated and labeled by incorporating biotin-16-UTP.
 
Hybridization protocol A total of 0.75 ug of biotin-labeled cRNA was hybridized for 16 hours to Illumina's Sentrix MouseRef-8 Expression BeadChips (Illumina, San Diego, CA, USA).
Scan protocol The arrays were washed and blocked. Biotinylated cRNA was detected with streptavidin-Cy3 and quantitated using Illumina's BeadStation 500X Genetic Analysis Systems scanner. The image data was extracted using BeadStudio software (Illumina).
Description none
Data processing The expression data were filtered to include only probes with a consistent signal on each chip; the cutoff value was established at P < 0.02. The resulting dataset was next analyzed with DIANE 6.0, a spreadsheet based microarray analysis program. Using DIANE, the background was subtracted from the raw signal intensity of each gene, and the results were normalized with a Z-Score transformation. Only 16 of the 64 total arrays are included in this GEO Archive file.

Data table header descriptions
ID_REF
VALUE The matrix table contains Z-Scores, which were calculated using the following equation: Z-Score(gene x) =(ln(gene x intensity) - ln(mean intensity of genes 1 to n))/stdev(intensity of genes 1 to n), where n is the number of genes on the array.
