Sample GSM622274 Query DataSets for GSM622274
Status Public on Feb 27, 2011
Title siGAPDH_2 [exon-level]
Sample type RNA
 
Source name HeLa cells (ATCC)
Organism Homo sapiens
Characteristics cell line: HeLa
trasfection: siRNA anti-GAPDH
Treatment protocol siRNAs were synthesized as ON-TARGET-PLUS grade from Dharmacon. Anti-HP1 and anti-GAPDH siRNAs were transfected twice consecutively with Dharmafect #1 (Dharmacon) according to the manufacturer’s instructions.
Growth protocol HeLa cells were grown in DMEM (Invitrogen) supplemented with 7% (v/v) fetal calf serum and 100 U.ml-1 penicillin-streptomycin.
Extracted molecule cytoplasmic RNA
Extraction protocol RNA was isolated with the RNeasy Mini Kit (Qiagen) with DNAseI (10U, Roche) treatment, according to the manufacturer’s instructions.
Label biotin
Label protocol Samples were enzymatically fragmented and biotinylated using the WT Terminal Labeling Kit (Affymetrix)
 
Hybridization protocol Samples were hybridized using Affymetrix hybridization kit materials • Heat cocktails at 99° for 5 minutes, then 42° for 5 minutes centrifuge at max speed for 1 minute (N.B. this deviates from Affy SOP). • Transfer 200μl of hyb solution to each array, then tape holes and parafilm. • Hybridize 16 hours at 45° at 60rpm• Fluidics washing is FS450_0001
Scan protocol Affymetrix Gene ChIP Scanner 3000 7G
Data processing Data were processed using EASANA from GenoSplice technology. GC background correction were applied to probe intensities (core), gene and exon level expression were summarized from the corrected intensities and then quantile normalized.
