|
| 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).

|
| 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.
