Sample GSM7528031 Query DataSets for GSM7528031
Status Public on Oct 31, 2023
Title Input_KO_S [mouse_Brd9_H3K27Ac-ChIP-seq]
Sample type SRA
 
Source name Lineage- bone marrow cells in femora and tibiae
Organism Mus musculus
Characteristics strain: C57BL/6
donor genotype: CD45.2(+) Mx1-Cre Brd9fl/fl
recipient genotype: CD45.1(+) CD45.2(-)
timing of preparation: 5 months after pIpC injection
chip antibody: None
Treatment protocol Four weeks after BMT, the recipient mice received 20 mg/kg pIpC injection every other day for a total of 3 doses.
Extracted molecule genomic DNA
Extraction protocol Cells were fixed with 2mM DSG (Thermo Fisher Scientific, 20593) for 30 min at room temperature and replaced with fixing buffer (50 mM HEPES-NaOH (pH 7.5), 100 mM NaCl, 1 mM EDTA) containing 1% paraformaldehyde (Electron Microscopy Sciences, 15714) and crosslinked for 10 min at 37°C.Crosslinking was quenched by adding glycine to a final concentration of 0.125 M. The nuclear fraction was extracted by first resuspending the pellet in 1 ml of lysis buffer (50 mM HEPES-NaOH (pH 8.0), 140 mM NaCl, 1mM EDTA, 10% glycerol, 0.5% NP-40, and 0.25% Triton X-100) for 10 min at 4°C. Cells were pelleted, and washed in 1 ml of wash buffer (10 mM Tris-HCL (pH 8.0), 200 mM NaCl, 1 mM EDTA) for 10 min at 4°C. Cells were then pelleted and resuspended in 1 ml of shearing buffer (10 mM Tris-HCl (pH 8), 1 mM EDTA, 0.1% SDS) and sonicated.Lysate was centrifuged for 5 min at 14,000 rpm to purify the debris. Then 100 ml of 10% Triton X-100 and 30 ml of 5M NaCl were added. The sample was then incubated with 20 ml of Dynabeads Protein G (LifeTechnologies,10003D) for 1 h at 4°C. Primary antibodies were added to each tube and immunoprecipitation (IP) was conducted overnight in the cold room. Cross-linked complexes were precipitated with Dynabeads Protein G for 2 hr at 4°C. The beads were then washed in low salt wash buffer (20 mM Tris-HCl pH 8, 150 mM NaCl, 10 mM EDTA, and 1% SDS) for 5 min at 4°C, high salt wash buffer (50 mM Tris-HCl pH 8, 10 mM EDTA, and 1% SDS) for 5 min at 4°C and LiCl wash buffer (50 mM Tris-HCl pH 8, 10 mM EDTA, and 1% SDS) for 5 min at 4°C. DNA was eluted in elution buffer (100 mM sodium bicarbonate and 1% SDS). Cross-links were reversed overnight at 65°C. RNA and protein were digested with 0.2 mg/ml RNase A for 30 min at 37C followed by 0.2 mg/ml Proteinase K for 1 h at 55°C. DNA was purified with phenol-chloroform extraction and isopropanol precipitation.
ChIP-seq libraries were prepared using the Rubicon ThruPLEX DNA-seq Kit from 1 ng of purified ChIP DNA or input DNA according to the manufacturer’s protocol.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NovaSeq 6000
 
Description genomic DNA immunoprecipitated without antibody
Data processing The adapter sequences were removed from the FASTQs using Trimmomatic (0.39).
The cleaned FASTQs were aligned using Bowtie2 (2.4.4) to the mouse reference genome mm10.
The duplicated reads were removed using picard (2.26.2) MarkDuplicates.
The bigWig files were generated using bamCoverage (3.5.1).
Assembly: mm10
Supplementary files format and content: bigWig
