Status Public on Mar 30, 2017
Title IgG-1
Sample type SRA
 
Source name brains
Organism Drosophila melanogaster
Characteristics developmental stage: 3rd instar larva
tissue: brains
chip antibody: IgG (Santa Cruz #2027)
genotype/variation: wild type
Extracted molecule genomic DNA
Extraction protocol Lysates from embryonic cells or 3rd instar brains were clarified from sonicated nuclei and histone-DNA or Nup-DNA complexes were isolated with specific antibody
Libraries were prepared according to Illumina's instructions for NextSeq® 500/550 High Output Kit v2 (FC-404-2005).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NextSeq 500
 
Data processing Raw fastq files were trimmed to remove low quality base calls using Trimmomatic, with parameter "LEADING:3 TRAILING:3 SLIDINGWINDOW:3:3 MINLEN:30".
Trimmed reads were aligned to dm3 using Bowtie2, allowing for only uniquely aligned reads (MAPQ > 10) to be reported.
Duplicate reads and mitochondria reads were removed using Samtools and Bedtools.
Significant peaks were called using MACS2, with parameter "--qvalue 0.05 -m 2 50".
Bedgraphs were generated using the command "bedtools genomecov", library sizes were normalized to 10 million reads per sample.
BigWig files were then converted from bedgraph files using command "bedGraphToBigWig".
Genome_build: dm3
Supplementary_files_format_and_content: bigwig files were converted from bedgraph files, which were generated using Bedtools. Scores were normalized to 10 million reads per sample.
