Sample GSM876131 Query DataSets for GSM876131
Status Public on Dec 01, 2013
Title Lu023
Sample type SRA
 
Source name OR_Ctrl
Organism Drosophila melanogaster
Characteristics strain: Oregon R
tissue: ovary
rip antibody: none
Growth protocol Oregon Red or transgenic newly-eclosed fruitflies were grown on corn syrup solids with yeast for 2~4 days before ovary dissection.
Extracted molecule total RNA
Extraction protocol Lysates were clarified from dissected Drosophila ovaries and RNA-Sm protein complexes were isolated with antibody. RNA was purified from the immunoprecipitate, reverse transcribed and made into doublestranded DNA. Libraries were prepared according to Illumina's instructions. Briefly, DNA was fragmented, ligated to adapters and PCR amplified with Illumina primers for 15 cycles. The resultant DNA was purified from an agarose gel and captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer following the manufacturer's protocols.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina Genome Analyzer II
 
Data processing A custom D. melanogaster expanded genome was made using the Drosophila genome (dm3, April 2006) and gene annotations. Filtered sequence reads (chastity >=0.6) were mapped to the expanded genome using Bowtie, allowing up to 2 mismatches and 10 mapped locations. Bowtie-mapped files were then analyzed using the ERANGE software to count the number of unique, spliced and multiple reads, and reads that mapped to putative new genes, measured as RPKM (reads per kb per million reads) values.
To create the wiggle files, sequence files were mapped to D. melanogaster expanded genome and output as sam files, and then converted to UCSC track files using samtools and BEDtools.
