Sample GSM3073018 Query DataSets for GSM3073018
Status Public on Oct 18, 2018
Title INPUT_C12-TAF15_CHA
Sample type SRA
 
Source name INPUT_C12-TAF15_CHA
Organism Mus musculus
Characteristics cell type: pre-B cells Arf-/-
strain: C57BL/6
passages: TAF15-ZNF384 Fusion
chip antibody: none
Growth protocol Cells were derived from C57BL/6 Arf-/- BM cells as described (Randle et al, PNAS, 2001). Cells were transduced with lentiviral supernatants of ZNF384-HA, TAF15-ZNF384-HA, or TCF3-ZNF384-HA.
Extracted molecule genomic DNA
Extraction protocol Chromatin was prepared as described (Zhang et.al, Nature Genetics, 2016). Breifly, 20 X 10^6 cells were crosslinked with 1% formaldehyde for 10 minutes. Cells were washed 3 times with PBS and lysed on ice for 10 minutes with lysis buffer. Chromatin was washed twice in wash buffer and once in shearing buffer before resuspending in 1ml of shearing buffer. Chromatin was sonicated with a Covaris E210 instrument and resuspended in dilution buffer. Finally, immunoprecipiation was performed with anti-HA antibody.
To prepare ChIP-seq libraries, 10 ng of ChIP DNA was end repaired and adaptor ligation was performed using the NEBNext ChIP-Seq Library Prep Reagent Set for Illumina (New England BioLabs). Libraries were purified after 14 rounds of PCR amplification with Q5 DNA Hot-Start polymerase (New England BioLabs). Each ChIP-seq library underwent 50-cycle single-end sequencing using TruSeq SBS kit v3 on an Illumina HiSeq 2000.

Description TAF15-ZNF384 Fusion
Data processing we mapped 50bp single-end reads to mouse genome mm9(MGSCv37) with BWA (version 0.7.12-r1039),
marked duplicated reads with Picard and only unique mapped reads extracted by Samtools (version 1.2) were kept for analysis.
We extend each read to estimated fragment size by SPP (version 1.1) and generated bigwig files scaled the track normalized to 15M unique mapped reads.
Review each sample find they have clear peaks by IGV (3.0.beta) and consistent between anti-HA samples and anti-ZNF384 samples.
Later we performed analysis only used the anti-HA samples since their peaks are stronger and most have ZNF384 motif where anti-ZNF384 samples were weak.
