| Title |
GFP(low)_r2 |
| Sample type |
RNA |
| |
|
| Source name |
hESC
|
| Organism |
Homo sapiens |
| Characteristics |
gender: female
cell line: H9
genotype/variation: GFP(low)
|
| Treatment protocol |
Human embryonic stem cells (hESCs) were genetically marked with LTR7-GFP followed by sorting by FACS, in order to collect GFP(high), GFP(+) and GFP(low) cells. HESCs were transfected with shRNA against GFP, LBP9 and HERVH, respectively.
|
| Growth protocol |
Human embryonic stem cells (hESCs) were maintained on plates coated with Matrigel in hESC medium (knockout DMEM, 20% knockout serum supplement, 1 mM L-Glutamine, 1% nonessential amino acids, 0.1 mM 2-Mercaptoethanol, 10 ng/ml bFGF and primocin) with mitomycin-C treated mouse embryo fibroblasts (MEFs).
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted from ~3x10E6 cells using the RNeasy Plus kit from Qiagen followed by the TURBO DNA-free™ DNase Treatment, according to the manufacturer's instructions. Quality control was performed with Agilent Bioanalyser.
|
| Label |
biotin
|
| Label protocol |
Biotin-labeled cRNA samples for hybridization on Illumina Human Sentrix-12 BeadChip arrays (Illumina, Inc.) were prepared according to Illumina's recommended sample labeling procedure
|
| |
|
| Hybridization protocol |
Hybridization is performed at 58°C, in GEX-HCB buffer (Illumina Inc.) at a concentration of 100 ng cRNA/µl, unsealed in a wet chamber for 20h. Spike-in controls for low, medium and highly abundant RNAs were added, as well as mismatch control and biotinylation control oligonucleotides.
|
| Scan protocol |
Microarray scanning was done using an iScan array scanner.
|
| Description |
GFP_neg_r2
|
| Data processing |
Intensities were extracted as data by BeadArray package which was processed using variance-stabilizing transformation (VST) by lumi package in R.
robust spline normalization (RSN) which combines the features of the quantile and loess normalization.
