Sample GSM2201115 Query DataSets for GSM2201115
Status Public on Jun 01, 2017
Title CD274+69+ DT-Treated ATAC Biological rep1
Sample type SRA
Source name CD 274,69 labeled mouse intestinal cells after DT treatment
Organism Mus musculus
Characteristics strain: B6;129 mixed background
cell type: Adult Epitheial cells; proximal 1/3 of intestine
genotype: Wild-Type
Treatment protocol Mice were injected with diphtheria toxin (50 µg/kg mouse weight) four times on alternate days, and sacrificed 1 day after the last injection.
Growth protocol Crypts from the proximal 1/3 of mouse small intestines were isolated by scraping off villi and incubating in 5mM EDTA in PBS for 45 minutes at 4°C. Crypts were disaggregated with 0.5U/ml Dispase in DMEM for 30 minutes at 37°C. Cell were stained with antibodies against CD69 (BV421 conjugate, BD Biosciences 562920 ) and CD274 (APC conjugate, BD Biosciences 564715) at 4°C for 30 minutes. CD 69+ 274+ cells were sorted by flow cytometry and immediately used for chromatin transposition.
Extracted molecule genomic DNA
Extraction protocol Whole nuclei were used for chromatin transposition using Nextera Tn5 Transposase (Illumina)
The transposed DNA was amplified using NEBNext High-Fidelity 2X PCR Master Mix (New England Biolabs), and 75 bp single-end reads were sequenced on an Illumina NextSeq 500 instrument.
