Sample GSM1702540 Query DataSets for GSM1702540
Status Public on Nov 02, 2015
Title HiSeq_H3_hi_CB_DMSO2
Sample type SRA
 
Source name Cord blood
Organism Homo sapiens
Characteristics tissue: Cord blood
immunprecipitation: Total H3
mnase for chromatin digestion: High
treatment: DMSO
Extracted molecule genomic DNA
Extraction protocol Mint-ChIP: Cells were lysed and native chromatin was digested using Mnase. Subsequently, nucleosomes were indexed by adapter ligation and pooled for immunoprecipiation of H3K9ac (Active Motif, 39917), H3K9me2 (Abcam, ab1220) and total H3 (Abcam, ab1791).
Mint-ChIP: Immunoprecipitated DNA was amplified by in vitro transcription, followed by reverse transcription. Resulting fragments, tagged on both ends, were amplified by PCR using primers compatible with Illumina sequencing.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
 
Description ChIP-seq
Data processing Provided fastq files are already demultiplexed according to adapter barcode and trimmed.
Alignment: BWA paired-end alignment to hg19
Filter1: Remove all unmapped reads and reads with X0 > 2 from bam files
Filter2: Remove all PCR duplicates using PicardTools MarkDuplicates with REMOVE_DUPLICATES=true VALIDATION_STRINGENCY=LENIENT
Filter3: Of pairs with identical R1 starting position alignment, keep only the pair with the longest fragment size.
Make tdf files using igvtools count --includeDuplicates --pairs
Genome_build: hg19
Supplementary_files_format_and_content: For visualization in IGV, tdf files are provided.
