Sample GSM1545000 Query DataSets for GSM1545000
Status Public on Dec 30, 2014
Title 24 month H3K4me1
Sample type SRA
Source name Hematopoietic stem cells (HSC)
Organism Mus musculus
Characteristics cell type: Murine bone marrow derived primary HSCs
cell surface marker: SP-KSL-CD150+
strain: C57BL/6
chip antibody: Abcam ab8895
Extracted molecule genomic DNA
Extraction protocol Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody.
Genomic DNA were extracted from the cells and fragmented to 200-500 bp via biorupter. Followed by immunoprecipitation with specific antibody, ChIPed DNA were successfully made library using ThruPLEX preparation kit without extra amplification (Rubicon, Ann Arbor, MI)
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
Description technical replicate of biological replicate 1
Data processing Reads were mapped with Bowtie2. Uniquely mapped reads were used for peak calling by Macs2 with multiple testing correction q value cutoff 0.01.
ChIP-seq reads were aligned to the mm9 genome assembly using Bowtie2 version 2.0.6 with 1 mismatch in seed allowed, command=bowtie2 -p12 -k 2 -N 1. Peak calling was performed on uniquely aligned reads (lacking bowtie2 flag XS:i) with Macs2 version, command=macs2 callpeak -f BAMPE -g mm -m 2 50 --verbose 3 --bdg --SPMR -t treatment.bam -c control.bam , where treatment is immunoprecipitate and control is input DNA.
Genome_build: mm9
Supplementary_files_format_and_content: The narrowPeak are BED6+4 format file which contains the peak locations together with peak summit, pvalue and qvalue. Definition of some specific columns are: 5th: integer score for display, 7th: fold-change, 8th: -log10pvalue, 9th: -log10qvalue, 10th: relative summit position to peak start. The bigWig files were created from the Macs2 bedgraph files, representing signal density of fragment pileup as signal per million reads More information may be found in the Macs2 documentation.
