Sample GSM1816075 Query DataSets for GSM1816075
Status Public on Jan 11, 2016
Title H3K27ac-A0
Sample type SRA
 
Source name Adult hematopoietic stem/progenitor cells (HSPCs)
Organism Homo sapiens
Characteristics tissue: Adult HSPCs (A0)
developmental stage/tissue: adult bone marrow
cell type: primary adult CD34+ HSPCs (A0)
chip antibody: H3K27ac
chip antibody vendor: Abcam
chip antibody cat. #: ab4729
Treatment protocol NA
Growth protocol Human primary fetal liver or adult bone marrow-derived CD34+ HSPCs and ProEs were cultured ex vivo using a serum-free two-phase liquid culture system.
Extracted molecule genomic DNA
Extraction protocol For ChIP-seq analysis using the Illumina HiSeq2500, 10-20 ng of ChIP DNA was processed for library generation using the ChIP-seq Sample Preparation Kit (Illumina) following the manufacturer’s protocol. Raw ChIP-seq data were processed using the Illumina software pipeline. Only ChIP-seq reads that aligned to exactly one location in the reference human genome (UCSC, hg18) were retained for downstream data analysis.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
 
Data processing Sequencing reads were aligned to human genome assembly hg18 (NCBI version 36) using Bowtie v0.12.7 with the following parameters: -v 2 -m 3 --strata --best. Duplicate reads were removed after the aligment with the Picard command-line tools.
Peak detection was performed with the Model-based Analysis of ChIP-Seq (MACS) algorithm (http://liulab.dfci.harvard.edu/MACS/).
The wig files were generated by a moving window of size 200bp. The tag count in the windown was further normalized in unit RPKM (# read per kb per million total reads) for ChIP-seq data generated by HiSeq 2000.
Genome_build: hg18
Supplementary_files_format_and_content: Mapped read bed file, wig file, and peak bed file
