Sample GSM1974912 Query DataSets for GSM1974912
Status Public on Jan 25, 2016
Title D.melanogaster roX2 (Even) ChIRP-seq (with transgenic D.melanogaster roX2)
Sample type SRA
 
Source name D.melanogaster mixed-sex wandering 3rd instar larvae
Organism Drosophila melanogaster
Characteristics tissue: whole larvae
developmental stage: third instar larval stage
gender: mixed
Growth protocol Larvae were raised at room temperature on standard cornmeal molasses or Wheeler-Clayton medium. Larvae were collected at wander third instar larval stage.
Extracted molecule genomic DNA
Extraction protocol DNA was extracted from recovered chromatin fraction by ChIRP by gentle elution with Rnase A and H, proteinase K digestion, and phenol-chloroform extraction.
ChIRP-seq libraries were prepared using NEBNext® ChIP-Seq Library Prep Master Mix Set for Illumina with standard TruSeq adapters.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NextSeq 500
 
Description Trans-MEL-roX2-merge.bedGraph
Trans-MEL-roX2-merge.bw
Data processing Data processing was performed following the ChIRP-seq pipeline (Chue et al., 2011). Reads were trimmed for adaptor sequence, mapped using bowtie to the respective Drosophila spp. genome, and Even and Odd pairs were merged. ChIRP-seq peaks were called using MACS2.
