Sample GSM180038 Query DataSets for GSM180038
Status Public on Apr 04, 2007
Title TGF-beta treated lung carcinoma cells at 1hr Exp 1
Sample type RNA
 
Channel 1
Source name lung carcinoma cells control
Organism Homo sapiens
Characteristics Lung carcinoma cells derived from caucasian male
Biomaterial provider Dr. Anita Roberts
Treatment protocol No treatment (Control for 5ng/ml TGF-beta1treatment), grown in recommended medium, washed with serum free medium and allowed to remain in serum free medium for 1hr before extraction of the sample.
Growth protocol Cells were plated in tissue culture dishes in DMEM with 10% Fetal Bovine Serum and other constituents, incubated at 37 degrees C in 5% CO2 and 90% humidity.
Extracted molecule total RNA
Extraction protocol RNA was Extracted using TRI reagent from Sigma Aldrich with an extra chloroform extraction and cleaned up using RNA easy mini columns.RNA was quantitated on a spectrophotometer and analyzed on a formaldehyde-agarose gel.
Label Cy3
Label protocol The labelling of the probe was done using the Micromax direct labelling kit (Perkin Elmer Life Sci.) according to the recommended protocol.
 
Channel 2
Source name lung carcinoma cells TGF-beta treated
Organism Homo sapiens
Characteristics Lung carcinoma cells derived from caucasian male

Treatment protocol Cells grown in recommended medium, washed with serum free medium and treated with 5ng/ml TGF-beta1 in serum free medium, for 1hr before extraction of the sample.
Growth protocol Cells were plated in tissue culture dishes in DMEM with 10% Fetal Bovine Serum and other constituents, incubated at 37 degrees C in 5% CO2 and 90% humidity.
Extracted molecule total RNA
Extraction protocol RNA was Extracted using TRI reagent from Sigma Aldrich with an extra chloroform extraction and cleaned up using RNA easy mini columns.RNA was quantitated on a spectrophotometer and analyzed on a formaldehyde-agarose gel.
Label Cy5
Label protocol The labelling of the probe was done using the Micromax direct labelling kit (Perkin Elmer Life Sci.) according to the recommended protocol.
 
 
Hybridization protocol The hybridisation was carried out in the GeneTAC Hyb Station (Genomic solutions, UK) at 65 degree for 4 hours, 60 degree for 4 hours and 55 degree for 10 hours. The slides were then washed with medium stringency (2X SSC and 0.1% SDS), high stringency (0.1X SSC and 0.1% SDS) and post wash (0.1X SSC) buffers for 5 minutes each, dried and scanned using a Scanner (Scanarray Express, Perkin Elmer life Sciences, USA).
Scan protocol Scanned using Scanarray Express (Perkin Elmer Life Sci), the software used for image aquisition was scanarray.
Description no additional information is necessary
Data processing All the image analyses have been done using the Quantarray software (Perkin Elmer Life Sciences, USA). Filtering and compilation of data have been done using Microsoft Excel and Microsoft Access. Spots of compromised quality and with low intensity were eliminated from the analysis. The data was normalized by LOWESS method (Avadis 3.1, Strand Life Sciences, India), Cy5:Cy3 ratios were established and log2 values were calculated.
