Sample GSM339271 Query DataSets for GSM339271
Status Public on May 28, 2009
Title MCF-7 cells_NAMPT knockdown_replicate 1
Sample type RNA
 
Source name MCF-7 cells NAMPT knockdown
Organism Homo sapiens
Characteristics MCF-7 cells NAMPT knockdown
Growth protocol MCF-7 cells were maintained in Eagle's minimum essential medium supplemented with 5% calf serum and antibiotics.
Extracted molecule total RNA
Extraction protocol Total RNA was prepared using Trizol reagent according to the manufacturer's instructions (Invitrogen) and was further purified using RNeasy columns (Qiagen)
Label Biotin
Label protocol Seven µg of total RNA were subjected to One-cycle Target Labeling Assay (Affymetrix) to generate biotinylated cRNA targets for hybridization to Affymetrix U133A 2.0 microarray
 
Hybridization protocol Standard hybridization to Affymetrix U133A 2.0 microarray
Scan protocol Standard scanning protocol using GeneChip Scanner
Description MCF-7 cells_NAMPT knockdown_replicate 1
Data processing The raw data were processed by Affymetrix GCOS software to obtain detection calls and signal values, and then normalized by scaling. Signals were then log2 transformed, median centered for the array, and median centered for each gene.
