Sample GSM138721 Query DataSets for GSM138721
Status Public on Jul 31, 2007
Title KELH0028_P-23_52M5
Sample type RNA
 
Channel 1
Source name Universal RNA
Organism Homo sapiens
Characteristics Tissue:Universal RNA
Biomaterial provider Stratagene
Treatment protocol none
Extracted molecule total RNA
Extraction protocol Universal human reference RNA was purchased from Stratagene and was amplified using MessageAMP aRNA kits (Ambion) as per manufacturer's instructions prior to labeling
Label Cy3
Label protocol Universal RNA probes was prepared by direct labeling of universal aRNA with Cy-3 fluorescent dye
 
Channel 2
Source name PBMC
Organism Homo sapiens
Characteristics Tissue:Blood, Patient id:P-23, Age:52, Sex:M, DSO:5, Status:pre-pO2 nadir
Biomaterial provider Dr. David Kelvin
Treatment protocol none
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using Paxgene blood collection tubes then amplified using the MessageAmp aRNA kit (Ambion) as per the manufacturer's instructions.
Label Cy5
Label protocol Sample probes were prepared by direct labeling with Cy-5 fluorescent dye
 
 
Hybridization protocol similar to direct labelling protocol listed at UHN Microarray facility web site.
Scan protocol Scanned at 16 bits using the Genepix Axon Scanner at 10micro-meter resolution at 635 nm (Cy5) and 532 nm (Cy3) using Genepix Pro 6.0 analysis software (Molecular Devices Corporation)
Description Peripheral blood was collected longitudinally from SARS patients during hospitalization into heparinized tubes and processed for further analysis within 2-3 hours of collection. RNA was stabilized and purified using Paxgene Blood Collection Tubes and Paxgene RNA kits (Qiagen, Mississauga, ON, Canada).
Data processing Each quantified output file was run though the following pre-processing steps using R (URL: www.r-project.org)and the Limma package. For Minimum Intensity filtering, R and G values were treated with a surrogate replacement policy for estimating sub-threshold values. The raw merged R and G channels were lowess-normalized (grouped by print-tip), normalized between chips using quantile normalization and transformed to log2 ratios (70).
