Status Public on Jan 20, 2015
Title Brain-Early-onset Alzheimer disease- 2
Sample type RNA
 
Source name Frozen brain tissue: posterior cingulate at thalamus level
Organism Homo sapiens
Characteristics gender: Female
age at death: 65
post-mortem interval (hours): 16:00
apoe genotype: 3/3
psen1 mutation: None
neuropathological data (braak stage): A3, B3, C3
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from frozen brain tissue (posterior cingulate area) using the RNeasy Lipid Tissue Mini Kit (Qiagen)
Label Biotin
Label protocol Labeled ssDNA was prepared according to the standard Affymetrix Terminal labeling Kit protocol.
 
Hybridization protocol Following fragmentation, 5 ug of ssDNA were hybridized for 16 hr at 45C following Affymetrix standard procedures
Scan protocol GeneChips were scanned according to the standard Affymetrix protocol (Affymetrix Genechip Command Console program 3.1.0.1228, scanner PlateScanner M10)
Description Gene expression data of final stages of Alzheimer's disease
Data processing Raw data was background adjusted, normalized and summarized by Robust Multi-array Analysis (RMA) using the Affy package (version 1.30.0) from Bioconductor on R language (version 2.13.2).
