Sample GSM4746310 Query DataSets for GSM4746310
Status Public on Aug 27, 2020
Title w1118 ChIP-seq rep1
Sample type SRA
 
Source name fly heads
Organism Drosophila melanogaster
Characteristics age: day 14
genotype: w;;
antibody: anti-V5 (Sigma A7345)
Growth protocol Flies were maintained on standard cornmeal-agar food at 25 °C in a 12 h:12 h light-dark cycle and under controlled humidity.
Extracted molecule genomic DNA
Extraction protocol ~8000 14-day-old flies per sample were collected 2 h before lights-on (ZT22), frozen in liquid nitrogen and maintained at -80 °C until processed. Heads were collected using metal sieves, and then, 1 ml of heads was ground in liquid nitrogen and homogenized 30 times in NE Buffer with 1% PFA. Lysates were clarified from sonicated nuclei and Fer2-DNA complexes were isolated with antibody.
Libraries were prepared with 0,5 to 0,7 ng of ChIP-enriched DNA as starting material and processed using the Illumina TruSeq ChIP kit according to the manufacturer’s specifications, at the iGE3 Genomics Platform in Geneva. The libraries were validated on a Tapestation 2200 (Agilent) and a Qubit fluorometer (Invitrogen - Thermo Fisher Scientific). Single reads of 50 bp were generated using the TruSeq SBS HS v3 chemistry on an Illumina HiSeq 2500 sequencer.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
 
Data processing ChIP-seq reads were aligned to the dm3 genome assembly using Bowtie2 with default settings
Peaks were called using MACS2 with default settings (q-value=0.05) by comparing each Fer2::GFP::V5 ChIP sample (N=2) to each w1118 ChIP sample (N=2; negative control). The 267 shared peaks overlapping in all the four FER2 ChIP vs w1118 ChIP comparisons were selected as confident peaks.
