Sample GSM594175 Query DataSets for GSM594175
Status Public on Oct 18, 2010
Title Untreated DGRC S2 Cells, Replicate 2
Sample type RNA
 
Source name DGRC S2 Cells, untreated
Organism Drosophila melanogaster
Characteristics cell type: S2 cells (DGRC)
Treatment protocol For RNAi experiments, S2 cells (DGRC) were harvested 96 hours after addition of dsRNA targeting NELF (NELF-B and NELF-E subunits; NELF-depleted), β-galactosidase (Mock-treated), or no addition (Untreated), as described in Armknecht, S. et al. (2005) Methods in Enzymology, 392: pp. 55-73.
Growth protocol S2(DGRC) cells were grown in M3 media (Sigma) supplemented with bacto-peptone and yeast extract + 10% FBS (GIBCO).
Extracted molecule total RNA
Extraction protocol The RNeasy RNA extraction kit (QIAGEN), with on-column DNAse digestion, was used according to manufacturer’s protocol
Label biotin
Label protocol Starting with 1ug of total RNA, biotin-labeled cRNA was produced using the Affymetrix 3' Amplification One-Cycle Target labeling kit according to manufacturer's protocol.
 
Hybridization protocol 15ug of amplified cRNAs were fragmented and hybridized to the array for 16 hours in a rotating hybridization oven using the Affymetrix Eukaryotic Target Hybridization Controls and protocol.
Scan protocol Slides were stained and washed as indicated in the Antibody Amplification Stain for Eukaryotic Targets protocol using the Affymetrix Fluidics Station FS450. Arrays were then scanned with an Affymetrix Scanner 3000 and data was obtained using the Genechip Operating Software (Version 1.2.0.037).
Description Gene expression analysis was conducted using Drosophila Genome 2.0 Genechip® arrays (Affymetrix, Santa Clara, CA). Starting with 1ug of total RNA, biotin-labeled cRNA was produced using the Affymetrix 3’ Amplification One-Cycle Target labeling kit according to manufacturer’s protocol. For each array, 10ug of amplified cRNAs were fragmented and hybridized to the array for 16 hours in a rotating hybridization oven using the Affymetrix Eukaryotic Target Hybridization Controls and protocol.
Data processing Affymetrix GeneChip Command Console (V. 1.1), Algorithm: ExpressionStat 5.0
The resulting files (.dat, .cel and .chp) were imported into the Rosetta Resolver system (Version 6.0). This system performs data pre-processing and error modeling as described in Weng (2006). Resolver generated fold-changes and p values, based on ratios built in the system, were exported for further analysis.
