| Title |
BRD-K98645985-treated ATAC-seq replicate 3 |
| Sample type |
SRA |
| |
|
| Source name |
CD8+ T cells
|
| Organism |
Mus musculus |
| Characteristics |
cell type: CD8+ T cells
genotype: Wild type
treatment: BRD-K98645985
|
| Treatment protocol |
WT CD8 T cells were treated with DMSO or 1uM BRD-K98645985 druing activation.
|
| Growth protocol |
Naïve CD8 T cells were activated with anti-CD3/28 and ICAM.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
50,000 cells were pelleted at 500 x g for 5 min at 4°C. Samples were washed in 1 ml cold PBS and resuspended in 50 ul cold cell lysis buffer (10 mM Tris pH7.4, 10 mM NaCl, 3 mM MgCl2, 0.1% NP-40). Nuclei were pelleted at 1000 x g for 10 min and resuspended in 50 ml transposition reaction mixture (25 ml TD buffer, 2.5 ml TDE1, 22.5 ml ddH2O) (20034197, Illumina). Samples were incubated at 42°C for 45 min. DNA was then purified using MiniElute PCR Purification Kit (28004, Qiagen). Libraries were barcoded and amplified with Q5 High-Fidelity 2x Master Mix (M0492S, NEB).

| Description |
First division

| Data processing |
Paired-end sequencing reads were trimmed with Trim Galore (version 0.5.0) with default parameters.
Reads were aligned to a hybrid genome of reference mouse mm10 assembly and drosophila Ensembl r97 using Bowtie 2 (version 2.3.5.1) with settings --end-to-end --very-sensitive -X 2000.
The BAM file was filtered with SAMtools (version 1.9), BamTools (version 2.5.1) and scripts of nf-core/chipseq to discard reads, mates that were unmapped, or PCR/optical duplicates, or not primary alignments, or mapped to multiple locations, or mapped to ENCODE blacklisted regions; only reads mapped in proper pair were kept (-F 1804 -f 2 -q 30). Reads mapped to nucleosome free regions were filter by insert size < 109.
Peaks were called using MACS (version 2.1.2) with narrowPeak setting, --extsize 200, and recommended mappable genome size (default value for other parameters).
Chromatin accessibility signal was normalized by scaling to 1 million mapped reads to spike-in using BEDTools (version 2.27.1) and bedGraphToBigWig (version 377) with default parameters.
Assembly: mm10
Supplementary files format and content: BigWig files scaling tag count to 1 million mapped reads of spike-in genome.
Supplementary files format and content: Bed files of peaks called using MACS2
