| Title |
MTA2_ChIP in Satb2KO colonic epithelium rep 1 |
| Sample type |
SRA |
| |
|
| Source name |
Intestine epithelium
|
| Organism |
Mus musculus |
| Characteristics |
genotyping: SATB2 KO
intestine part: Colon
|
| Treatment protocol |
Epithilal tissues were collected by the EDTA method 30 days after tamoxifen injection and cross-linked with 2mM DSG and 1% formaldehye.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
50 µl of pelleted cross-linked cells were resuspended in 350 µl sarkosyl lysis buffer (0.25% sarkosyl, 1 mM DTT and protease inhibitor in RIPA buffer) and sonicated at 15% amplification by a tip sonicator (Qsonica, Q125) to obtain 200bp to 800bp chromatin fragments. Diluted lysates were incubated with TFs antibodies at 4°C overnight and were additionally incubated with 30 µl protein A/G magnetic beads. ChIPed DNA was purified with a MinElute purification kit.
Libraries were prepared using the ThruPLEX DNA-Seq Kit
Exactly followed the protocol from Takara bio, R400428. All final libraries were size selected (200-800 bp) by AMPure XP beads (Beckman, A63880) and loaded for sequencing.

| Description |
MTA2_ChIP
|
| Data processing |
All reads were trimmed with trim_galore (https://www.bioinformatics.babraham.ac.uk/projects/trim_galore/), and subjected to quality control with FastQC before and after adapter trimming.
Bowtie2 (Langmead and Salzberg, 2012) was used to align the two independent ChIP-Seq analyses to the mouse (mm10) genome with default parameters.
Aligned ChIP-Seq data in SAM format were transformed to BAM files and non-uniquely mapped reads were filtered-out.
Duplicate alignments were then marked and removed using Sambamba.
The merge function in samtools was used to merge the BAM files of different replicates and filter out non-uniquely mapped reads.
Deeptools bamCoverage (duplicate reads ignored, RPKM normalized) was used to generate bigWig files from BAM files.
Assembly: Mouse mm10
Supplementary files format and content: Bigwig files for visualization of TFs genomic binding peaks.
