Sample GSM5956419 Query DataSets for GSM5956419
Status Public on Jul 19, 2022
Title ChIP-seq Cp190-KO Input replicate 2
Sample type SRA
Source name Cultured cells
Organism Drosophila melanogaster
Characteristics cell line: CP-R6
mutation: Cp190[3]
antibody: none
Treatment protocol none
Growth protocol Cells were grown to confluence in Schneider's medium (Lonza) supplemented with 10% FBS, 100U/ml of Penicillin G, 100ug/ml of Streptomycin sulfate
Extracted molecule genomic DNA
Extraction protocol Live cells were crosslinked with 1.8% formaldehyde for 10 min at 25C. Soluble chromatin was prepared and immunoprecipitation performed as described in Kahn et al. Nucleic Acids Res. 2016. 44:10132-10149
2ng of immunoprecipitated DNA were processed using NEBNext Ultra II DNA Library preparation Kit for Illumina (cat# E76455) and index oligonucleotides from NEBNext Multiplex Oligos for Illumina (cat# E7335).
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model HiSeq X Ten
Data processing Base calling and quality score assignment were done with HiSeq Control Software 2.2.58/RTA 1.18.64
Bcl to FastQ conversion was performed using None from the CASAVA software suite. The sequence read quality was reported in Sanger/phred33/Illumina 1.8+ scale.
Reads were aligned to the dm3 genome assembly using bowtie2 and the following parameters --phred33 -p 8.
Reads with MAPQ scores less than 30 were removed using samtools view -q 30
Genomic read count profiles were computed from the filtered bowtie2 alignments using pyicos convert software and the following parameters -f sam -F bed_wig -x 180 -O.
The resulted read count profiles were normalized to the number of corresponding MAPQ 30 filtered sequencing reads using custom R script
Assembly: dm3
Supplementary files format and content: Read count profiles in wig format
Supplementary files format and content: bed in dm6 transferred by UCSC liftover from above wig, example
