Sample GSM3583929 Query DataSets for GSM3583929
Status Public on Feb 12, 2019
Title FVB/129P2 backcross 1 H3K27ac ChIPseq
Sample type SRA
Source name FVB/129P2 backcross 1
Organism Mus musculus
Characteristics strain: FVB/129P2 backcross
antibody: H3K27ac
genotype/variation: Cdkn2ab
Extracted molecule genomic DNA
Extraction protocol Cells were fixed in 1% formaldehyde; 50mM Hepes-KOH; 100mM NaCl; 1 mM EDTA; 0,5 mM EGTA. Cell lysis was performed in LB1 buffer with final pH 7,5 (50 mM Hepes-KOH; 140mM NaCl; 1mM EDTA, 10% Glycerol, 0.5% NP-40; 0,25% Triton X-100; Proteinase inhibitor) for 20 minutes at 4°C. Subsequently, nuclei were lysed using LB2, pH 8,0 (10mM Tris-HCl; 200 mM NaCl; 1mM EDTA; 0,5mM EGTA; Proteinase inhibitor) for 10 minutes at 4°C. Pellets were resuspended in LB3 pH8,0 (10mM Tris-HCl; 100mM NaCl; 1 mM EDTA; 0,5mM EGTA; 0.1% Na-Deoxycholate; 0.5% N-lauroylsarcosine; Proteinase inhibitor). Crosslinked chromatin was sheared (400-800 bp) using a Covaris S2 with Tube and Caps (Covaris, 520048), using the following settings: duty cycle: 10%, intensity: 4, cycles per burst: 200 time 40 seconds with 20 cycles. Chromatin precipitation was performed overnight using antibody-bound (CTCF 5 l, SMC1 10 l, Igg 10 per IP) proteinA coupled DynaBeads (Invitrogen). Elution and decrosslinking was performed overnight at 65°C in EB pH 8,0 (50mM Tris-HCl; 10mM EDTA; 1% SDS). Samples were treated with Proteinase K and RNAseA for 2 hours. DNA was isolated using phenol extraction and ethanol precipitation.
Library preparation was done using a KAPA Library preparation kit using the manufacturer’s protocol.

Description rep1.narrowPeak
Data processing Reads were mapped to GRCm38 using bowtie2 with default settings.
Peak calling was performed using MACS2 (v2.1.1) (Feng et al., 2012) using IgG as control.
