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.
