Sample GSM1199045 Query DataSets for GSM1199045
Status Public on Mar 27, 2014
Title S2_ChIPseq_with_ecd
Sample type SRA
 
Source name S2 cells
Organism Drosophila melanogaster
Characteristics cell type: S2 cells
agent: ecdysone
chip antibody: anti-EcR monoclonal antibody (DDA2.7) developed by C. Thummel in D. Hogness laboratory
Treatment protocol For all experiments cells were treated with ecdysone. The final concentration of ecdysone was 41 μM (10 mg of 20-hydroxyecdysone (Sigma; cat. no. H5142) per 500 ml of growth medium). After 24 hrs incubation with the hormone, cells were harvested.
Extracted molecule genomic DNA
Extraction protocol 10^8 cells with and without treatment were harvested. Chromatin was sonicated with Tip sonicator (Omni Sonic Ruptor 250 Watt Ultrasonic Homogenizer) for 7 cycles (1 min on (duty cycle 30%, output 20%)) 1 min off) in 2 ml of Lysis buffer 3. The anti-EcR monoclonal antibody (DDA2.7) developed by C. Thummel in D. Hogness laboratory was obtained from the Developmental Studies Hybridoma Bank developed under the auspices of the NICHD and maintained by The University of Iowa, Department of Biology, Iowa City, IA 52242. 1 ml of chromatin was incubated with 3 μl of antibody (135 μg/ml) overnight. Chromatin and 25 μl of blocked Dynabeads Protein G (Invitrogen, cat. no. 10004D) were combined and incubated at 4° C for additional 2 hrs. 3 ng of material was used for library generation. Library was constructed following instructions of NEBNext® DNA Library Prep Reagent Set for Illumina® (NEB; cat. no. E6000L). Library amplifcation was done using KAPA Library Amp Real Time (KAPA biosystems: cat.no. KK2701).

Description S2_ChIPseq_with_ecd_rep1
S2_ChIPseq_with_ecd_rep2
PCR amplified DNA
Data processing Basecall where performed using Real-Time Analysis (RTA) version > 1.12.4.2 or CASAVA 1.9.1
Reads were mapped to the dm3 genome using bowtie (bowtie -p 12 -f -X 2000 -v 3 -m 1 --best --strata --quiet INDEX -1 reads_1.fa -2 reads_2.fa) excluding chrU, chrUextra, and chrM.
ChIP-seq peaks were called using STARR-seq pipeline using following parameters: -M 50 -W 1000 -D 600 -Z 1.67 -g dm3 -P 0.001
Genome_build: dm3
Supplementary_files_format_and_content: ChIP-Seq processed files supplement_ChIP_peaks_no_ecd.txt and supplement_ChIP_peaks_with_ecd.txt contain chr, summit, enrichment and p-values for called peaks.
