Sample GSM540568 Query DataSets for GSM540568
Status Public on Jul 04, 2011
Title P001
Sample type genomic
 
Channel 1
Source name Frozen tissue biopsy
Organism Homo sapiens
Characteristics tissue: Pancreatic Ductal Adenocarcinoma
Growth protocol Tumor samples from patients with either pancreatic ductal adenocarcinoma, adrenocortical carcinoma, or prostate carcinoma were flash-frozen and maintaned at -80 degrees C until processed for flow sorting
Extracted molecule genomic DNA
Extraction protocol 25-100 mg of tumor was thawed then minced in the presence of NST and DAPI. Each sample was then mechanically sheared then filtered through a 30 micron mesh filter prior to sorting. All sorting was done with an Influx Flow Cytometer equiped with a UV laser. DNA was extracted from each sorted fraction using Qiagen DNA micro kits. All phi29 amplifications were done with a 100ng aliquot of either sample or reference genomic DNA using the GenomiPhi kit (G.E Health Care).
Label Cy5
Label protocol A 1 microgram aliquot of each sample and reference DNA was digested with DNAse 1 then labeled with a fluorescent nucleotide (Cy5 for tumor and Cy3 for normal reference) using the BioPrime labeling kit (Invitrogen)according to manufacturer's protocol.
 
Channel 2
Source name Reference pooled 46XX
Organism Homo sapiens
Characteristics tissue: pooled normal (46,XX) reference (Promega)
Growth protocol Tumor samples from patients with either pancreatic ductal adenocarcinoma, adrenocortical carcinoma, or prostate carcinoma were flash-frozen and maintaned at -80 degrees C until processed for flow sorting
Extracted molecule genomic DNA
Extraction protocol 25-100 mg of tumor was thawed then minced in the presence of NST and DAPI. Each sample was then mechanically sheared then filtered through a 30 micron mesh filter prior to sorting. All sorting was done with an Influx Flow Cytometer equiped with a UV laser. DNA was extracted from each sorted fraction using Qiagen DNA micro kits. All phi29 amplifications were done with a 100ng aliquot of either sample or reference genomic DNA using the GenomiPhi kit (G.E Health Care).
Label Cy3
Label protocol A 1 microgram aliquot of each sample and reference DNA was digested with DNAse 1 then labeled with a fluorescent nucleotide (Cy5 for tumor and Cy3 for normal reference) using the BioPrime labeling kit (Invitrogen)according to manufacturer's protocol.
 
 
Hybridization protocol Labeled DNAs were hybridized in an ozone free environment in a rotisserie oven at 20 rpm for 40 hours then washed according to array supplier's (Agilent)protocol
Scan protocol All arrays were scanned using an Agilent 2565C Scanner and default settings for CGH.
Data processing Data was extracted from the TIFF files using Agilent FE 10.5. The data quality was assessed using the QC Report output in F.E. 10.5. All arrays that passed the experimental Q.C. were then visulaized and analyzed using DNA Analytics 4.0.85 and the ADM2 step gram algorithm.
