Sample GSM846070 Query DataSets for GSM846070
Status Public on Jan 04, 2012
Title Tet1-KD ES cells siRNA #1 48hr, rep2
Sample type RNA
 
Source name E14Tg2a Embryonic Stem Cells
Organism Mus musculus
Characteristics cell line: E14Tg2a
transfection: Tet1 siRNA #1
Extracted molecule total RNA
Extraction protocol Total RNA was extracted using RNAeasy kit (Qiagen)
Label biotin
Label protocol Labeling was performed using Affymetrix's IVT labeling kit following manufacturer's directions.
 
Hybridization protocol One hundred ng of total RNA was amplified as directed in the Affymetrix 3' IVT Express kit protocol, performing the IVT reaction for 16 hours. 12.5 μg of amplified biotin-aRNAs were fragmented and 10 μg were hybridized to Affymetrix 430 2.0 array for 16 hours at 45°C in a rotating hybridization oven using the Affymetrix Eukaryotic Target Hybridization Controls and protocol. Array slides were stained with streptavidin/phycoerythrin utilizing a double-antibody staining procedure and then washed for antibody amplification according to the GeneChip Hybridization, Wash and Stain Kit and user manual.
Scan protocol Arrays were scanned in an Affymetrix Scanner 3000 and data was obtained using the GeneChip® Command Console Software (AGCC; Version 1.1).
Data processing Data was processed by performing background correction, quantile normalization, and calculation of expression set summaries using the Robust Multichip Average (RMA) protocol (Irizarry et al. (2003); Biostatistics 4: pages 249-264) as implemented in the affy packge from Bioconductor (http://www.bioconductor.org). Gene-specific probesets were constructed using the Entrez Gene – centric custom CDF, version 13 (Dai et al. (2005); Nucl Acids Res 33: e175). Log-scale data was further normalized by 1) setting the per-sample median to 6.5 and 2) subtracting the per-gene median.
