Sample GSM6172856 Query DataSets for GSM6172856
Status Public on Dec 27, 2022
Title HisC, 5.5-6h, H2AK9ac, rep2
Sample type SRA
 
Source name whole embryo
Organism Drosophila melanogaster
Characteristics cell line: whole embryo
cell type: Drosophila embryo 5.5-6h AEL
genotype: Df(2L)HisC, P{GAL4-twi.2xPE}/ Df(2L)HisC, P{UAS:eYFP}AH2
antibody: H2AK9ac (Active Motif, #39110)
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 or 5.5 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 Kaya-Okur et al., 2019
Libraries were constructed following Kaya-Okur et al., 2019, using the listed antibodies, libraries were generated using Epicypher 15-1017-EPC and 15-1018-EPC

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
NarrowPeak representation was used for histone marks H3K4me3, H2K27ac with following settings: -f BAMPE --keepdup all -p 5e-4 --call-summits. For histone marks enriched in broad domains including H3K36me3, H3K27me3, H2AK9ac, and H2BK16ac, the broadPeak representation was used applying following settings: -f BAMPE --keepdup all -p 5e-4 -b 0.01.
bigwig files required for coverage tracks as well as heatmaps were generated using Deeptools v3.3.1
Assembly: dm6
Supplementary files format and content: bigWig, bed containing peaks
