Sample GSM123271 Query DataSets for GSM123271
Status Public on Jul 27, 2007
Title brain_healthy_control_sampleid_jg1744
Sample type RNA
 
Source name human post-mortem brain tissue, healthy control
Organism Homo sapiens
Characteristics Disease_status: Healthy control
Age (years): 54
Gender: Male
Post mortem interval (hours): 10
Braak stage: II
Cause of death: Aortic aneurysm
Biomaterial provider Prof. Anthony Holland, Cambridge Brain Bank, Department of Pathology, Addenbrooke's Hospital, University of Cambridge, UK
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from human postmortem brain tissue using Trizol (Invitrogen, USA) or Tri reagent (Sigma, UK) total RNA isolation kits according to the manufacturer's instructions.
Label Biotin
Label protocol Double-stranded cDNA was synthesised from 5 micrograms of total RNA using Superscript II double-stranded cDNA synthesis kit (Invitrogen, USA), purified, then in-vitro transcribed and labelled using BioArray HighYield RNA transcript Labeling Kit (Enzo Life Sciences, USA)
 
Hybridization protocol Following fragmentation, 15 micrograms of cRNA were hybridised to Affymetrix Human Genome 133A GeneChips for 16 hours at 45oC with constant rotation at 60rpm. Chips were washed and stained according to manufacturer's instructions using the Affymetrix GeneChip Fluidics Station 400.
Scan protocol Affymetrix HG-U133A GeneChips were scanned with the Agilent GeneArray Scanner
Description none
Data processing The raw data (CEL files) were read into R statistical package and normalised using the robust multi-chip average (RMA) method (Irizarray et al, 'Exploration, normalization and summaries of high density oligonucleotide array probe level data', Biostatistics, 2003).
