Sample GSM949008 Query DataSets for GSM949008
Status Public on Jun 29, 2012
Title Fcp1-RNAi replicate 2
Sample type SRA
 
Source name S2 cell line
Organism Drosophila melanogaster
Characteristics cell line: S2
genotype/variation: Fcp1
Growth protocol Cells were grown in M3 media (Sigma) supplemented with bacto-peptone and yeast extract + 10% FBS
Extracted molecule total RNA
Extraction protocol Ten million nuclei were allowed to run-on for 10 minutes at 30°C in a reaction containing ATP, CTP, GTP, and BrUTP. The RNA was isolated using Trizol and acid phenol extractions. The RNAs were base hydrolyzed to an average length of 100-150 nucleotides, and RNAs with incorporated BrU were purified with 2 immunoprecipitations successive using Anti-BrdUTP agarose. The RNA was treated with PNK and polyadenylated using E. coli polyA polymerase to add 50-100 As to their 3’ ends. The polyadenylated RNA was reverse transcribed used with the following bar coded oligonucleotides (INOO3: 5’-pTAGAGATCGTCGGACTGTAGAACTCT-iSp18-CAAGCAGAAGACGGCATACGATTTTTTTTTTTTTTTTTTTTVN, INOO4: 5’-pTGATGATCGTCGGACTGTAGAACTCT-iSp18-CAAGCAGAAGACGGCATACGATTTTTTTTTTTTTTTTTTTTVN). The first 4 bases have the bar-code and iSp18 indicates an 18 carbon spacer between two oligo linkers used for Illumina sequencing. The resulting DNA was gel extracted and circularized using Epicentre CircLigase, and PCR amplified for 12-15 cycles. The cDNA was then sequenced on the Illumina Genome Analyzer.
 
Library strategy RNA-Seq

Instrument model Illumina Genome Analyzer
 
Description GRO-seq
Nuclear run on with 5-BromoUTP for immunopurification
Data processing Barcode removed and read trimmed to 26nt
Adapter removed using cutAdapt with all possible combinations of VN and a threshold of 0.2
Aligned with bowtie to dm3, allowing two mismatches and requiring unique alignment (-m1).
converted bowtie .sam file to the .bed file standard.
Genome_build: dm3
Supplementary_files_format_and_content: bed file; the reads were trimmed to 26 nucleotides, and mapped to non-repetitive regions of the Drosophila genome using Bowtie.
