| Title |
WT_ES_rep2 |
| Sample type |
RNA |
| |
|
| Source name |
mouse wild-type (WT) ES cells, replicate 2
|
| Organism |
Mus musculus |
| Characteristics |
cell line: Line J1
genotype: wild-type
cell type: embryonic stem (ES) cells
|
| Treatment protocol |
The cells were recovered by trypsinization and used for RNA preparation.
|
| Growth protocol |
ES cells were cultured in Glasgow Minimum Essential Medium (GMEM, Sigma) supplemented with 10% KNOCKOUT Serum Replacement (Invitrogen), 10 micro-M human adrenocorticotrophic hormone (Kurabo), 0.1 mM nonessential amino acids, 1 mM sodium pyruvate, 0.1 mM 2-mercaptoethanol, and 2000 U/ml leukemia inhibitory factor, on gelatinized culture dishes without feeder cells.
|
| Extracted molecule |
cytoplasmic RNA |
| Extraction protocol |
Cytoplasmic RNA was isolated by using the RNeasy Mini Kit (Qiagen) according to the manufacture's cytoplasmic RNA protocol with DNase digestion option. RNA was quantified and quality controlled using the NanoDrop ND-1000 Spectrophotometer (Thermo) and the 2100 Bioanalyzer (Agilent).
|
| Label |
Cy3
|
| Label protocol |
Amplification and Cy3 labeling of RNA was prepared from 50 ng of RNA using the Low Input Quick Amp Labeling kit (Agilent) according to the manufacturer's instructions (G4140-90040 One-Color Microarray-Based Gene Expression Analysis Protocol Version 6.5). Purification of Cy3-labeled cRNA was performed using the RNeasy Mini Kit (Qiagen). Quantity, quality and dye incorporation of Cy3-labeled cRNA were checked using the NanoDrop ND-1000 Spectrophotometer (Thermo) and the 2100 Bioanalyzer (Agilent).
|
| |
|
| Hybridization protocol |
600 ng of Cy3-labeled cRNA was hybridized in Agilent hybridization chambers for 17 hours at 65 degrees C and 10 rpm according to the manufacturer's instructions (G4140-90040 One-Color Microarray-Based Gene Expression Analysis Protocol Version 6.5).
|
| Scan protocol |
Slide scanning was performed using the Agilent DNA Microarray Scanner G2505C with 3 um resolution and 20-bit dynamic range.
|
| Description |
Gene expression data from wild-type ES cells
|
| Data processing |
The scanned images were processed with Feature Extraction Software 10.7.3.1 (Agilent) using default parameters (protocol GE1_107_Sep09 and Grid 028005_D_F_20110406) to generate background subtracted and spatially detrended green Processed Signal intensities. Normalize signal intensities were obtained by a) removal of data of control probes, b) removal of data of outlier probes (gIsFeatNonUnifOL flag = 1 or gIsFeatPopnfOL flag = 1 in any of samples), c) log2 transformation, and d) quantile normalization, which was performed using the normalizeQuantiles function of the limma package of the R.
