Sample GSM2774797 Query DataSets for GSM2774797
Status Public on Dec 06, 2017
Title ChIPseq_antiH3K9me3_dysgenic_rep2
Sample type SRA
 
Source name antiH3K9me3_dysgenic
Organism Drosophila melanogaster
Characteristics genotype: F1 dysgenic progeny: (females) w[1118] vs. (males) Harwich
developmental stage: Adult
tissue: Ovary
chip antibody: anti-H3K9me3 (Abcam, catalog# ab8898, lot# GR271507-1)
Treatment protocol no treatment
Growth protocol Flies were grown at standard conditions at 18º C
Extracted molecule genomic DNA
Extraction protocol IP and input libraries were prepared using NEBNext® Ultra™ II DNA Library Prep Kit for Illumina®
ChIP on formaldehyde-crosslinked ovaries was performed as previously described (Rozhkiv et al, 2013 - Genes Dev), using 100-200 dissected adult ovaries as starting material and the anti-H3K9me3 (Abcam, ab8898).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
 
Description anti-H3K9me3 ChIP-seq from dysgenic F1 progeny
Data processing ChIP-seq analysis was performed on the Galaxy web-based platform following previously described methods (Han et al, 2015 - Bioinformatics). Illumina adaptors and other low quality sequences were removed using the ‘Trim Galore!’ package. ChIP-seq input and IP filtered data were mapped to the Drosophila genome (dm3) and transposon consensus sequences using Bowtie2, using the -k = 1 parameter.
RNA-seq: Paired-end (100-nt-long reads) RNA-seq data were mapped to the Drosophila melanogaster genome (dm3) and the FlyBase and Repbase transposon consensus database using the piPipes package (version 1.5.0; https://github.com/bowhan/piPipes), following the RNA-seq pipeline as previously described (Han et al., 2015 - Bioinformatics). Briefly, libraries were first aligned to ribosomal RNA using Bowtie2. Non-rRNA reads were then mapped to the transcriptome and transposon consensus using Bowtie2.
Genome_build: Drosophila melanogaster dm3
