Sample GSM3259734 Query DataSets for GSM3259734
Status Public on Jul 07, 2018
Title aIRF9_IRF9WT_STIM_3_CHIP
Sample type SRA
 
Source name splenic NK cells
Organism Mus musculus
Characteristics genotype: IRF9WT
antibody: IRF9
condition: IFNaIL2
Extracted molecule genomic DNA
Extraction protocol Protein was cross-linked to DNA with 1% formaldehyde. Clarified supernatant from sonicated nuclei were applied to antibody-bound beads. After de-crosslinking and elution, DNA was isolated using Qiagen Gel Extraction Kit. Input samples were clarified supernatant that were not applied to antibody-bound beads.
Immunoprecipitated DNA was quantified by Picogreen and size was evaluated on a HighSense BioAnalyzer chip. When possible, fragments between 100 and 600 bp were size selected and Illumina Hiseq libraries were prepared using the Kapa DNA library preparation chemistry (Kapa Biosystems) using 12-15 cycles of PCR. Adaptors were diluted 1/10 or 1/50 depending on the starting amount of material available. Barcoded libraries were run on Hiseq 2500 1T in a 50bp/50bp Paired end run, using the TruSeq SBS Kit v3 (Illumina). An average of 57 million paired reads were generated per sample.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
 
Description Irf9_ChIP_peaklist_ZeroBasedCorrected.bed
Data processing BCL files were converted to fastq using bcl2fastq (v1.8.3 and v1.8.4)
ChIP-seq reads were aligned to the mm10 genome assembly using Bowtie2 (v2.2.9).
Peak-calling was done on concordantly aligned paired reads using MACS2 (2.1.1.20160309).
BigWig files were generated by converting BAM files to size-normalized BEDGRAPH files using bedtools (v2.26.0) and converted to bigWig using UCSC's bedGraphToBigWig (v4).
Genome_build: mm10
Supplementary_files_format_and_content: bigWig files are unscaled. BED file consists of IDR-thresholded (IDR < 0.01) peak list.
