Sample GSM6172799 Query DataSets for GSM6172799
Status Public on Dec 27, 2022
Title HisC, 7.5-7h, ATACseq, rep1
Sample type SRA
 
Source name whole embryo
Organism Drosophila melanogaster
Characteristics cell line: whole embryo
cell type: Drosophila embryo 6.5-7h AEL
genotype: Df(2L)HisC, P{GAL4-twi.2xPE}/ Df(2L)HisC, P{UAS:eYFP}AH2
antibody: none
Treatment protocol Maintaining flies used for embryo collection: controlled light conditions (24h light on), new apple agar plates were provided with yeast twice a day, raised at 25°C
Growth protocol Experimental design: Flies were raised on apple agar petri dishes in acrylic cages for 30 minutes for egg laying at 25°C, petri dishes were exchanged with new ones and embryos were further incubated at 25°C for 3.5, 4.5, 5.5 and 6.5 hours
Extracted molecule genomic DNA
Extraction protocol Embryos were washed with PBST and dechorionated in 50% bleach, mutant embryos were identified by eYFP expression. Nuclei were extracted following Buenrostro et al., 2015
Libraries were constructed following Buenrostro et al., 2015 using NEB Hifi 2x PCR master mix M0541S
 
Library strategy ATAC-seq
Library source genomic
Library selection other
Instrument model Illumina HiSeq 4000
 
Data processing Nextera Transposase adapter and low quality bases were eliminated using TrimGalore v0.6.6 and Cutadapt v1.17.
Reads were mapped to the Drosophila melanogaster reference genome dm6 (FlyBase Dmel Release 6.23) assembly using bowtie2 v2.3.4.2.
Mapped pairs were further filtered to maintain mapping quality above 10, as well as FR orientation concordant alignments, using custom scripts and samtools v1.9
PCR duplicates and mitochondrial reads were removed by sambamba v0.6.7 as well as reads blacklisted by the ENCODE project
Peaks of accessible chromatin were identified for each sample using MACS2 v2.1.2 with the following settings: -f BED --nomodel --shift -100 --extsize 200 --keep-dup all after converting the bam to bed file
Assembly: dm6
Supplementary files format and content: bigWig
