Sample GSM4284363 Query DataSets for GSM4284363
Status Public on Jul 28, 2021
Title CtrlPolII1_Rep1
Sample type SRA
 
Source name cell culture
Organism Drosophila melanogaster
Characteristics antibody: RBP1 (Diagenode Cat No-15200004) / Lot No 001-11
cell type: Embryonic
cell line: S2R+ Cells
Treatment protocol dsRNA was transfected in S2R+ cells by serum starvation for 6 hours. The treatment was repeated two times and cells were harvested 5 days after the first treatment.
Growth protocol Drosophila S2R+ cells were cultured in Schneider Cell’s Medium (GIBCO, Cat No-21720) supplemented with 10% FBS and 2% Penicillin/Streptomycin
Extracted molecule genomic DNA
Extraction protocol S2R+ cells were fixed with 1% formaldehyde for 3 min at room temperature, and harvested in SDS buffer resuspended in RIPA buffer (140 mM NaCl, 10 mM Tris-HCl [pH 8.0], 1 mM EDTA, 1% Triton X-100, 0.1% SDS, 0.1% DOC), and lysed by sonication. The lysate was cleared by centrifugation, and incubated with respective antibodies overnight at 4ºC. Antibody complexes bound to protein G beads, were washed once with 140mM RIPA, four times with 500mM RIPA, one with LiCl buffer and twice with T.E buffer for 10 minutes each at 4ºC.
After checking enrichment the recovered DNA was converted into libraries using NebNext Ultra DNA library preperation kit, following manufacturer's protocol
NebNext UltraII
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NextSeq 500
 
Description Pol II ChIP from S2R+ cells depleted for LacZ
Data processing De-multiplexing and fastq file conversion was performed using blc2fastq (v.1.8.4)
Mapping was performed using bowtie2 (v. 2.3.3) against ensembl release 84 of BDGP6 for Drosophila.
After mapping reads were filtered for uniquely mapping reads using the XS flag.
UCSC compatible library normalised bigwig tracks were produced using samtools version 1.2, ucsc tools (bedGraphToBigWig from 04-11-2012) and bedtools (v. 2.25.0) and custom scripts
