Sample GSM2091064 Query DataSets for GSM2091064
Status Public on Dec 07, 2016
Title MeRIP2
Sample type SRA
 
Source name MeRIP, S2R+ cells
Organism Drosophila melanogaster
Characteristics cell line: S2R+ cells
cell type: embryonic cells
rip antibody: anti-m6A
Treatment protocol no treatment
Growth protocol S2R+ cells were grown on standard conditions at room temperature
Extracted molecule polyA RNA
Extraction protocol Total RNA was isolated using Trizol reagent (Invitrogen). mRNA was purified by using two rounds of purification with Dynabeads Oligo (dT)25 (Invitrogen)
NEBNext Ultra directional Kit (NEB) was used omitting RNA fragmentation step for recovered m6A-RIP samples and following the manufacturer`s protocol for input samples.
 
Library strategy OTHER
Library source transcriptomic
Library selection other
Instrument model Illumina MiSeq
 
Description library strategy: MeRIP-Seq
Data processing The samples were sequenced on two flowcells on the Illumina MiSeq (MiSeq Control Software Version 2.6.1.1). Readlength was 68 bp SR
Mapping was done using Star (v. 2.4.0h), secondary alignments were filtered. Mapping was done against BDGP6 (ensembl release 79).
After mapping peaks were called using MACS (v.1.4.1, parameters: "--nomodel --shiftsize 65 --to-small -w -S --keep-dup all --call-subpeaks --nolambda -g 90464385 ).
After peakcalling peaks were split into subpeaks using PeakSplitter (v.1.0).
Consensus peaks were obtained by intersecting subpeaks of both replicates ( using BEDTools (v.2.25.0)).
For each consensus peak the coverage was calculated as counts per million (CPM) for each of the samples and averaged for input and MeRIP samples. Foldchanges for MeRIP vs Input were calculated based on these.
