Extracted molecule genomic DNA
Extraction protocol We manually conjugated antibody against cell type markers, such as GFAP, Nestin, Vimentin, PSA-NCAM, or Doublecortin to Dynabeads. We then used the Dynabeads-conjugated antibody to purify cells dissociated from SVZ microdissection. Briefly, cells from fresh dissected baboon SVZ were immediately dissociated with Accutase, equilibrated in binding buffer containing phosphate-buffered saline (PBS), 0.05% TritonX-100 (or saponin, detergent choice depends upon antibody), and subsequently subjected to Dynabeads-conjugated antibody purification. After elution with high salt and pH-gradient buffer, the purified populations were crosslinked in 1.1% formaldehyde before chromatin shearing by Diagenode Bioruptor. The resulting sheared chromatin fragments in a size range between 200 to 500 base pairs were incubated with H3K9me3 antibody-conjugated Protein A Dynabeads (Millipore #07-473, Upstate #07-442; Active Motif #39162; Life Technology Dynabeads protein A) overnight. For normalization, the aliquot of sheared chromatin fragments were incubated with antibody against total histone 3-conjugated Protein A Dynabeads (unmodifiedH3 antibody, Millipore #05- 499; 1:1000). Subsequently, enriched chromatin fragments were eluted, subjected to de-crosslink, purified for library preparation (Illumina Library Kit) and sequenced with 200millinon tags through Illumina HiSeq2000 sequencer.
Libraries were prepared according to instructions for Illumina Library Kit, Illumina TruSeq v2. Total H3 reads are maintained in GEO Sample GSM1413005.
