Sample GSM1061002 Query DataSets for GSM1061002
Status Public on Feb 09, 2013
Title ChIP-seq input Tj-GAL4->piwi
Sample type SRA
Source name ChIP-seq input Tj-GAL4->piwi
Organism Drosophila melanogaster
Characteristics tissue: ovaries
age: 3-5 days
chip antibody: none (input)
Treatment protocol ovaries were dissected on ice
Growth protocol flies were kept at 25 degrees
Extracted molecule genomic DNA
Extraction protocol ChIP-seq: chromatin from 50 ovaries was fragmented on Bioruptor during 14 min (2 cycles, 7 min each), an aliquot was kept as "input", the rest was used for ChIP with H3K9me-ab. The detailed protocols can be found in the Rozhkov et al, 2013
The detailed methods described in the Rozhkov et al. 2013
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina MiSeq
Data processing Reads were aligned to consensus drosphila transposon sequences (v9.4.1 available from using bowtie2 (version 2.0.0-beta7) and the following parameters: -p2 -k 10 -N1
Reads were separately aligned to the dm3 genome using bowtie2 and the same parameters
For ChIPseq libraries, peaks were identified using SICER (version 1.1) and the following parameters: redundancy threshold =1, fragment size = 250, window size = 500, gap size = 500, FDR = 0.05, effective genome size = 0.72
Genome_build: dm3
