Sample GSM1824808 Query DataSets for GSM1824808
Status Public on Dec 23, 2015
Title AA15m H3K27ac
Sample type SRA
 
Source name MGH15m H3K27ac
Organism Homo sapiens
Characteristics material type: Frozen Anaplastic Astrocytoma Surgical Resection
chip antibody: H3K27ac (cat 39133), Active Motif
idh1 status: Mutant (R132H)
Growth protocol Neurosphere cultures were maintained in Neurobasal media supplemented with 20 ng/mL recombinant EGF (R and D Systems), 20ng/mL FGF2 (R and D Systems), 1X B27 supplement (Invitrogen), 0.5X N2 supplement (Invitrogen), 3mM L-glutamine, and penicillin/ streptomycin.
Extracted molecule genomic DNA
Extraction protocol Cultured cells or minced tissue was fixed in 1% formaldehyde and snap frozen in liquid nitrogen and stored at -80ºC for at least overnight. Sonication of tumor specimens and gliomaspheres was calibrated such that DNA was sheared to between 400bp and 2000bp. CTCF was immunoprecipitated with a monoclonal rabbit CTCF antibody, clone D31H2 (Cell Signaling 3418). H3K27ac was immunoprecipitated with an antibody from Active Motif (cat 39133).
ChIP DNA was used to generate sequencing libraries by end repair (End-It DNA repair kit, Epicentre), 3’ A base overhang addition via Klenow fragment (NEB), and ligation of barcoded sequencing adapters.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NextSeq 500
 
Data processing Reads were aligned to hg19 using BWA.
Resulting alignment files were filtered to remove PCR duplicates and reads mapping to >2 sites genome-wide
ChIP-Seq density tracks were generated with ‘igvtools count’.
Genome_build: hg19
Supplementary_files_format_and_content: TDF density files were generate by igvtools
