Sample GSM159847 Query DataSets for GSM159847
Status Public on Feb 15, 2008
Title Control_rep2
Sample type RNA
 
Source name 15µg RNA, control experiment, replicate 2
Organism Mus musculus
Characteristics Strain: B6.C3Sn, Gender: Female, Age : Adult, Tissue : forebrain
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from a wild-type forebrain and treated with DNAse using Nucleospin RNA L kit (Macherey-Nagel) according to the manusfacturer’s instructions.
Label Cy5
Label protocol 15µg of total RNA were labelled by reverse-transcription in the presence of 7.5µM random hexamers (GE Healthcare), 250µM dUTP-Cy5 (GE Healthcare) and 100U Rtases Reverse-iT Blend (ABgene) overnight at 37°C.
 
Hybridization protocol RNG-MRC_MM25k_EVRY microarrays (Le brigand et al., NAR, 2006) were first incubated in a humid chamber for 2 hours to rehydrate the spots then placed for 1 hour in a dessicator and blocked for 1 hour at room temperature in 50mM Sodium Borate pH 9, 0.003% ethanolamine. Slides were then washed 5 minutes with water and dried by centrifugation.
Hybridizations were performed in 50% formamide, 5X Denhardt’s, 4x SSC and 0.1% SDS solution at 42°C for 16 hours. Microarrays were then washed at room temperature 5 minutes in 2X SSC, 0.1% SDS, 5 minutes in 1X SSC, 5 minutes in 0.2X SSC and 5 minutes in 0.05X SSC. Slides were finally dried by centrifugation 4 minutes at 900rpm.
Scan protocol Microarray images were obtained using a ScanArray Gx scanner (Perkin Elmer) with laser power = 90% and PMT gain = 80%.
Median signal and median local background intensities were extracted from the images using Mapix v2.2.4 software (Innopsys).
Description Second replicate of control experiment performed with 15µg total RNA without amplification.
Data processing Intensity/background ratios were calculated for each spot in each experiment.
Features which were not interpretable in all the 9 experiments performed were excluded for further analysis. For comparing experiments, the sum of F/B values for each slide was then multiplied by a correcting factor so that the sum of the corrected ratios was equal in all experiments.
