Sample GSM986303 Query DataSets for GSM986303
Status Public on Jan 03, 2017
Title H3K27m3 ChIP-seq for piwi mutated flies
Sample type SRA
 
Source name ovary
Organism Drosophila melanogaster
Characteristics strain: piwi1/2
tissue: ovary
antibody: H3K27m3
Treatment protocol Dissected ovaries (> 50 pairs) were homogenized in 1.5ml tubes .
Growth protocol 20 degrees C
Extracted molecule genomic DNA
Extraction protocol Proteins were extracted using 300mM KCl buffer D. Equal amounts of ovarian extract were incubated with antibodies for 2 hours, followed by incubation with Protein A-conjugated Dynabeads (Invitrogen) for 2 hours. Beads were then washed with 0.05% T/PBS, and immunoprecipitates eluted by 2X loading buffer.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
 
Description ChIP-seq
Data processing All the collected sequences from HiSeq2000 are mapped back to Drosophila melanogaster, which is dm3 from USCS genome browser. Up to 3 mismatches are allowed during the mapping process. The sequences that are mappable are subject to the MACS peak calling. Peaks with p-value less than 10-4 are retained for analysis.
Genome_build: dm3
Supplementary_files_format_and_content: text format, in which sequences that were mapped to genome are listed , together with their count number.
