Sample GSM1140940 Query DataSets for GSM1140940
Status Public on Jul 22, 2013
Title Sodium citrate 2mM, biological rep3
Sample type RNA
 
Source name Jurkat, P18
Organism Homo sapiens
Characteristics passage: P18
cell type: Human T cell
agent: Sodium citrate 2mM
cell line: Jurkat, Clone E6-1
Treatment protocol Jurkat cells (passage number 16 to 20) were seeded in 2.7 ml medium per well in 6-well plates (750,000 cells/well) . After growing the cells for 20 hours, exposure was initiated by adding 0.3 ml medium containing non-cytotoxic concentration of the compounds or vehicle controls. Subsequently, cells were exposed to the compounds for 6 h. The final DMSO concentration in the medium was 0.1% (v/v) for all the samples. Each exposure was performed in quadruplicate at four different days.with 0,7% NaCl, 0,04% triton-X100 and placed on ice in the Trizol solution (GibcoBRL).
Growth protocol The Jurkat cells were grown in RPMI-1640 medium supplemented with 10% heat inactivated Fetal Calf Serum (FCS), 2 mM glutamine, 1 mM sodium pyruvate, 1 mM non-essential amino acids, 100 U/ml penicillin, and 100 µg/ml streptomycin. Cells were cultured at 37 °C with 5% CO2 in a humidified atmosphere. The medium was refreshed every 2 days.
Extracted molecule total RNA
Extraction protocol RNA was isolated by using Qiagen QIAshredder kit according to the manufacturer’s protocol. RNA purification was done using Qiagen miRNeasy Mini kit.
Label biotin
Label protocol cDNA synthesis and subsequent synthesis of biotin-labeled cRNA was performed using GeneChip One-Cycle Target Labeling and Control Reagents including the One-Cycle cDNA Synthesis Kit, Poly-A RNA Control Kit, Sample Cleanup Module, IVT Labeling Kit, and Hybridization Control Kit (all from Affymetrix) according to the manufacturer’s protocol.
 
Hybridization protocol cRNAs were hybridized to the arrays for 16 hours at 45 °C (GeneChip Hybridization Oven 640; Affymetrix). Washing and staining were done by using GeneChip hybridization station, Fluidics Station 450, Affymetrix.
Scan protocol GeneChips were scanned by Affymetrix GeneChip Scanner 3000 7G.
Data processing Raw data were extracted using GeneChip Operating Software (Affymetrix). In order to filter out probes with sub-optimal specificity for the encoding genes, custom CDF files were generated from the raw data files, by using the R package available at http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/14.1.0/entrezg.asp. Then robust multichip average (RMA) normalization was applied to the complete dataset (Bioconductor). BioConductor packages were used for the quality control of the microarray data (www.arrayanalysis.org).
