Sample GSM4770939 Query DataSets for GSM4770939
Status Public on Dec 31, 2020
Title 48hpf_Pou3f3b_Sox10_double_positive_FoxC_mutant_ATAC_rep1
Sample type SRA
 
Source name 48hpf_Pou3f3b_Sox10_double_positive_FoxC_mutant_ATAC
Organism Danio rerio
Characteristics developmental stage: 48h post fertilization
cell type: dorsal intermediate domain neural crest cell
genotype/variation: Foxc1KO
Extracted molecule genomic DNA
Extraction protocol Cells were purified by FACS-sorting. chromatin were digested by tn5 transposase at 37°C for 20 minutes.DNA fragments were extracted using MiniElute columns (Qiagen), and then amplified by PCR.
FACS-sorted cells were centrifuged at 500 g for 20 m at 4 °C, and the pellet was suspended with 20 μL of lysis buffer (10 mM Tris HCl (pH 7.4), 5 mM MgCl2, 10% DMF, 0.2% N-P40) by pipetting 6-10 times to release the nuclei without purification. The cell lysate was then mixed with 30 μL reaction buffer (10 mM Tris HCl (pH 7.4), 5 mM MgCl2, 10% DMF, and homemade Tn5 Transposase) by vortexing for 5 s. The reaction was incubated at 37°C for 20 minutes, followed by DNA purification using a Qiagen MinElute kit.
Libraries were amplified by PCR with indexed primers
DNA fragments are amplified by PCR for 5 cycles using NEBnext master mix, with primers containing various indexes. Additional cycles are determined by qPCR on 1/10 of the amplified libraries. After amplification, the libraries are cleaned using AMPURE beads, to only keep the fragments larger than 100bp. The libraries are pooled before sequencing. 
 
Library strategy ATAC-seq
Library source genomic
Library selection other
Instrument model NextSeq 550
 
Data processing For ATACseq, reads were trimmed based on quality score and then aligned to reference mouse genome (mm10) using bowtie2. PCR-duplicates were removed by Sambamba, and then peaks were called by MACS2 from individual replicate using filter q value < 0.01.
