Sample GSM2350857 Query DataSets for GSM2350857
Status Public on Nov 01, 2016
Title 133_BA25
Sample type genomic
 
Source name BA25
Organism Homo sapiens
Characteristics tissue: cortex, Brodmann area 25
age: 42
groupid: non-psychiatric sudden death
gender: M
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was isolated from ~50 mg of each dissected brain region using a standard phenol-chloroform extraction method, and tested for degradation and purity before analysis.
Label Cy3 and Cy5
Label protocol 500 ng DNA from each sample was sodium bisulfite-treated using the EZ-96 DNA Methylation-Gol Kit (Zymo Research) according to the manufacturer's standard protocol.
 
Hybridization protocol Samples were processed according to the Illumina Infinium HumanMethylation450K BeadChip (Illumina) protocol.
Scan protocol Samples were assessed using the Illumina Infinium HumanMethylation450K BeadChip (Illumina) using a Illumina iScan System (Illumina).
Description 9297962043_R04C01
Data processing Illumina Genome Studio software was used to extract the raw signal intensities of each probe (without background correction or normalization). Probes containing a SNP with minor allele frequency (MAF) >5% within 10bp of the single base extension site based on Illumina's database and probes identified by Chen et al. (Epigenetics 2013, 8:203-209) were removed. Data was then pre-processed in the R package wateRmelon using the pfilter and dasen functions.
