E7.75_heart_cell40 |
| Sample type |
SRA |
| |
|
| Source name |
heart
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6
age: E7.75
cell type: heart cell
chip antibody: H3K27ac, Abcam, ab4729, Lot: GR3205526-1
|
| Growth protocol |
Mice were housed under a 12-12-hour light-dark cycle and allowed standard laboratory take care.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Crosslinked cells were treated with 0.3% SDS at 62°C. Transposition was set up by incubation at 55°C for 30 min, followed by addition of stopping buffer. Soluble chromatin was used for following ChIP experiments. DNA was eluted from beads, reverse crosslinked and treated with proteinase K. Finally, DNA was extracted by pheno-chloroform.
After PCR enrichment using NEBNext Q5 Ultra II master mix, products were purified and selected by AMPure XP beads for 200-1000 bp.

| Data processing |
Basecalls performed using CASAVA version 1.8.2.
Sequenced reads were trimmed and filtered by cutadapt (v 1.11) to get high quality reads.
High quality reads were aligned to mouse genome mm10 by bowtie2 (v 2.3.1), with parameter of "-N 1".
Reads whose MAPQ >= 30 were determined as uniquely mapping reads. Duplication reads were removed by Picard.
Peaks were called by MACS2 (v 2.1.1), with parameter of "--broad"
Bigwig files were generated from bam files using deeptools (v 2.2.3) bamCoverage. All samples were normalized to 10 million reads with binsize as 50 bp by “--scaleFactor, --binSize 50” parameters.
Genome_build: mm10
Supplementary_files_format_and_content: The processed files were bed files of non-duplicated reads.
