Title |
Brg1 knockdown ATAC-seq replicate 2 |
Sample type |
SRA |
|
|
Source name |
Brg1 knockdown ATAC-seq, ESC
|
Organism |
Mus musculus |
Characteristics |
strain: 46C (129/Ola strain) cell line: ESC line 46C transfection: shRNA vector targeting Brg1, 48h timepoint, replicate 2
|
Treatment protocol |
described in the SAMPLES section (experimental conditions)
|
Growth protocol |
Embryonic stem cells were cultured at 37°C, 5% CO2, on mitomycin C-inactivated mouse embryonic fibroblasts, in DMEM (Sigma) with 15% foetal bovine serum and leukemia inhibitory factor (LIF).
|
Extracted molecule |
genomic DNA |
Extraction protocol |
50,000 cells were collected, washed with cold PBS and resuspended in 50ul of ES buffer (10 mM Tris pH 7.4, 10 mM NaCl, 3 mM MgCl2). Permeabilized cells were resuspended in 50 ul Transposase reaction (1X Tagmentation buffer, 1.0-1.5 ul Tn5 transposase enzyme (Illumina)) and incubated for 30min at 37°C. Subsequent steps of the protocol were performed as described in PMID: 24097267. Transposed DNA was subjected to several round of amplification with Ad2 primer pairs (the reverse primer contains the index allowing subsequent multiplexing. Oligonucleotide sequences are available in PMID: 24097267). Libraries were next purified using a Qiagen MinElute kit and Ampure XP magnetic beads (1:1.6 ratio) to remove remaining non ligated adapters.

Description |
library strategy: ATAC-seq

Data processing |
Basecalling was performed with RTA 1.18.64. Bcl conversions into Fastq and demultiplexing were performed using bcl2fastq version 1.8.3, Sequenced reads were trimmed for adaptor sequence and masked for low-complexity/low-quality sequence with Trimmomatic 0.32, then mapped to mm9 whole genome using bowtie v0.12.7 with parameters -a -m1 --best --strata -v2 p3 Genome_build: mm9 Supplementary_files_format_and_content: wig files were generated using WigMaker 3 with default parameters; Scores represent the maximum number of reads overlapping in a 25 bp bin Supplementary_files_format_and_content: BIGWIG files were generated with UCSC tools (v4) using WigToBigWig program
