Sample GSM520522 Query DataSets for GSM520522
Status Public on Mar 01, 2011
Title GBM_stem_4 days_1
Sample type RNA
 
Source name glioblastoma stem cells, stem, 4 days
Organism Homo sapiens
Characteristics tissue: brain
disease status: glioblastoma
cell type: stem cells G48
Treatment protocol glioblastoma stem cells were differentiated in the presence of FCS for 4 days
Growth protocol Tumor cells were then resuspended in serum-free DMEM/F12 medium (Invitrogen, Carlsbad, CA) containing human recombinant EGF (20 ng/ml; Sigma, St. Louis, MO), bFGF (20 ng/ml; Sigma), B-27 (20 ml per ml of medium; Invitrogen) and heparin (2 mg/ml), and plated at a density of 3x106 live cells/60-mm plate
Extracted molecule total RNA
Extraction protocol The cells were harvested with TRIzol Reagent (Invitrogen) and the RNA was extracted according to the manufacturer's instructions. As a last step of the extraction procedure, the RNA was purified with the RNeasy Mini-kit (Qiagen, Hilden, Germany).
Label biotin
Label protocol The cDNA was prepared from 5 microg total RNA using the One –Cycle cDNA Synthesis kit from Affymetrix. This cDNA was used for synthezising the cRNA using the IVT labeling kit (Affimetrix). The synthezised cRNA was purified with the GeneChip Sample Cleanup Module (Affimetrix).
 
Hybridization protocol Following fragmentation, 15 microg of cRNA were hybridized to the Affymetrix HG-U133A 2.0 chip according to the protocols provided by the manufacturer.
Scan protocol GeneChips were scanned using the GeneChip Scanner 3000 from Affymetrix.
Description G48_SC.CEL
Data processing Data analysis performed using R (2.8.1) and Bioconductor packages. The function rma of package affy (1.20.2) was used for normalization.
