Extraction protocol |
Briefly, 20 million cells were crosslinked in 37oC prewarmed culture medium with 1% formaldehyde for 10 min at RT. Cells were then treated with cell lysis buffer (5 mM PIPES pH 8, 85 mM KCl, 0.5% NP-40) for 10 min on ice, followed by treatment with nuclei lysis buffer (50 mM TrisCl pH 8.1, 10 mM EDTA, 1% SDS) for 10 min at RT. Chromatin was subjected to sonication with Diagenode Bioruptor at 4oC to achieve an average size of 200-300 bp (30 sec on, 30 sec off, 20 cycles with high energy input). Chromatin was then precleared with Dynabeads Protein A at 4oC for 2 hours. 1/30 lysates were kept as input and the rest were incubated with 5 ug RAD21 antibody (Abcam, ab992) overnight at 4oC. IP samples were then captured by Dynabeads Protein A at 4oC for at least 2 hours, followed by bead washing and elution. IP and Input DNA were de-crosslinked at 65oC overnight and purified via Qiagen PCR purification columns. Purified DNA was subjected to ChIP-Seq library preparation with Illumina Truseq ChIP Sample Preparation Kit (Illumina, IP-202-1012).

Description |
aligned to mm9 genome
|
Data processing |
Library strategy: ChIP-Seq
Reads were aligned to mm9 genome using bowtie 2.2.8 with --non-deterministic flag
Unmapped reads were filtered using samtools 1.8
wig files were produced using RSeQC tool 2.6.3 and normalized to a coverage of 10 million 100nt reads for display
Peak calling was performed using MACS2 with the following commands:
macs2 callpeak -t IP.bam -n Result_directory --nomodel --extsize 51 --nolambda -B --SPMR -g mm --verbose 0 –broad
Genome_build: mm9
Supplementary_files_format_and_content: wig files contain peak information for samples, bed files contain peak calling information.
