Sample GSM3187766 Query DataSets for GSM3187766
Status Public on Aug 27, 2019
Title Experiment A - 0.6 units AluI
Sample type SRA
 
Source name Experiment A - 0.6 units AluI
Organism Mus musculus
Characteristics strain: NIH/S
gender: Female
age: E13.5
tissue: liver
treatment: 0.6 units AluI
Treatment protocol Nuclei were prepared from homogenised liver and digested with increasing amounts of the restriction enzyme AluI.
Growth protocol Livers were dissected from female NIH/S mice (E13.5) and stored at -80C.
Extracted molecule genomic DNA
Extraction protocol AluI digestion was stopped and the DNA was sonicated.
Purified sonicated DNA was prepared for Illumina paired-end sequencing using New England Biolabs kit E7370. 50-nt paired reads were obtained using an Illumina NextSeq-500 machine.
New method: Quantitative DNA accessibility assay - "qDA-seq"
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina NextSeq 500
 
Description HepD-2_A3
Data processing Sequences were aligned to the Mus musculus genome (mm10) using Bowtie2 with the parameters -X 5000 --very-sensitive
For every AluI motif (AGCT) found in the genome, we estimated the fraction of nuclei in which the given motif was cleaved by AluI, f_cut = N_cut=(N_cut + N_uncut), by counting the number of reads that were cut at this site (with an end at this site), N_cut, and the number of reads that were not cut at this site (overlapping the motif), N_uncut, using the Bioinformatics toolbox from Matlab.
Genome-wide profiles (bw files) containing the fraction of cut DNA at each site were generated using Matlab and wigToBigWig.
Genome_build: mm10
Supplementary_files_format_and_content: bigwig files containing the fraction of cut DNA at each AluI site along the mouse genome (for IGV genome browser)
