Sample GSM424889 Query DataSets for GSM424889
Status Public on Nov 30, 2009
Title Retina wildtype 42 days 3
Sample type RNA
 
Source name Retina, 42 days old wildtype mice
Organism Mus musculus
Characteristics strain: C57/Bl6
gender: male
genotype: Egr-1 wildtype
age: 42 days
tissue: retina
Treatment protocol Mice were killed by an overdose of diethylether at the mean age of 30 days (p29-p31) or 42 days (p41-p43). Afterwards, the eyes were enucleated, the retinas were prepared and immediately snap-frozen in liquid nitrogen. The retinas of 12 homozygous Egr-1 knock-out mice (hm) and 12 wildtype mice (wt) of the same strain were prepared for both time points (48 animals in total).
Growth protocol Animals were housed in standard cages with their littermates under a 12 hours light/dark cycle with unrestricted access to water and food pellets. Illumination was provided by standard fluorescent lamps and was approximately 200 lux.
Extracted molecule total RNA
Extraction protocol Three single retinas from different mice were pooled to obtain 4 samples per group (wt30, wt42, hm30, hm42), and RNA was isolated using the RNeasy Mini Kit (Qiagen, Hilden, Germany) according to the manufacturer's instructions. The quality of total RNA was monitored by Agilent 2100 Bioanalyzer (Agilent Technologies, Palo Alto, CA) following the manufacturer's instructions.
Label Biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 1.5 ug total RNA (see manufacturer´s website: Expression Analysis Technical Manual, One-Cycle Target Labeling Assay, Affymetrix).
 
Hybridization protocol see manufacturer's website
Scan protocol Scanning and analysis were carried out using the Affymetrix Microarray Suite Software (version 5.0)
Description RNA sample consists of three separate retinal samples that were pooled
Data processing Signal intensities were analyzed using ArrayAssist 4.0 (Stratagene, La Jolla, CA). Transformation algorithm: GC-RMA.
