Title |
D3_V5_ChIPSeq |
Sample type |
SRA |
|
|
Source name |
ES-D3
|
Organism |
Mus musculus |
Characteristics |
cell line: ES-D3 cell type: embryonic stem cells genotype: wild type chip antibody: anti- V5 (Invitrogen R960-25)
|
Treatment protocol |
Cells were cross-linked for 5 minutes at room temperature with 1% formaldehyde-containing medium; cross-linking was stopped by PBS-glycine (0.125 M final). Cells were washed twice with ice-cold PBS, scraped, centrifuged for 10 min at 4000 rpm, 4 'C and pellets flash-frozen in liquid nitrogen and stored at - 80 'C until lysed.

Extracted molecule |
genomic DNA |
Extraction protocol |
Cell pellets were thawed in ice and resuspended in cell lysis buffer (5 mM PIPES, pH 8.0, 85 mM KCl, and 0.5% NP-40, 1 ml/15 cm plate) and incubated for 10 min on ice. Lysates were then centrifuged for 10 min at 4000 rpm. Nuclear pellets were resuspended in 6 volumes of sonication buffer (50 mM Tris-HCl, pH 8.1, 10 mM EDTA, 0.1% SDS), incubated on ice for 10 min, and sonicated to obtain DNA fragments below 2000 bp in length (Covaris S220 sonicator, 20% Duty factor, 200 cycles/burst, 100 peak incident power, 32 cycles of 20" on and 40" off). Sonicated lysates were cleared by centrifugation and 800 μg of chromatin was diluted in RIPA buffer (10 mM Tris-HCl, pH 8.0, 1 mM EDTA, 0.5 mM EGTA, 1% Triton X-100, 0.1% SDS, 0.1% Na-deoxycholate, 140 mM NaCl) to a final concentration of 0.8 μg/μl, precleared with Protein A sepharose (GE Healthcare) for 2 hours at 4°C and immunoprecipitated overnight with 8 μg of antibodies. 4% of the precleared chromatin was saved as input. Immunoprecipitated DNA was purified with the Qiagen QIAquick PCR Purification Kit, eluted in 60 μl of water and used for library preparation. Libraries were prepared with the Illumina ChIP-seq DNA sample preparation kit according to manufacturer instructions (for input DNA we used only 150 ng of DNA)

Data processing |
Base-calling performed with CASAVA by the Vincent J. Coates Genomics Sequencing Laboratory at UC Berkeley ChIP-seq reads quality control performed with FastQC (version 0.10.1) ChIP-seq reads were aligned to the mm10 genome assembly using bowtie (version 0.12.8) with the following configurations: -n 2 -m 1 ChIP-Seq peaks were called using MACS2 (version 2.1.0.20140616) with the following configurations: -t <sample.bam> -c <input.bam> -f BAM -g mm --nomodel --extsize 250 bigWig coverage files were generated with deepTools (version 2.4.1) with the following configurations: bamCoverage -of bigwig --binSize 50 --normalizeTo1x 2150570000 --extendReads 250 --ignoreDuplicates Genome_build: mm10 Supplementary_files_format_and_content: ChIP-seq: tdf files were generated using igvtools (igvtools count -w 50 -e 200) / txt files are Partek detected enriched regions RAD23B vs. IgG); RNA-seq: text files contain CuffDiff results
