Sample GSM3781241 Query DataSets for GSM3781241
Status Public on Sep 16, 2020
Title STRAP Embryo eCLIP Input
Sample type SRA
 
Source name embryo
Organism Mus musculus
Characteristics tissue: embryo
strain: C57BL/6
age: prenatal day 9.5
genotype: wild type
Growth protocol EB cells were cultured in ES medium without LIF and then cultured in N2B27 medium supplemented with 10ng/ml bFGF for additional 5 days.
Extracted molecule total RNA
Extraction protocol UV-crosslinked EBs or embryos were lysed in CLIP lysis buffer followed by sonication and STRAP-RNA complexes were isolated with anti-STRAP antibody.
eCLIP libraries were prepared for sequencing using eCLIP-seq protocols.
 
Library strategy OTHER
Library source transcriptomic
Library selection other
Instrument model Illumina NextSeq 500
 
Data processing Library strategy: eCLIP-seq
Basecalls performed using Illumina's bcl2fastq version 2.18.0.12
Cutadapt version was used to trim primer adapters from raw FASTQ files using parameters: -f fastq --match-read-wildcards --times 1 -e 0.1 -O 1 --quality-cutoff 6 -m 18 -a NNNNNAGATCGGAAGAGCACACGTCTGAACTCCAGTCAC -g CTTCCGATCTACAAGTT -g CTTCCGATCTTGGTCCT
To remove repetive elements, STAR version 2.5.2b was used on the trimmed FASTQ files using paramters: --outSAMunmapped Within --outFilterMultimapNmax 30 --outFilterMultimapScoreRange 1 --outSAMattributes All --outStd BAM_Unsorted --outSAMtype BAM Unsorted --outFilterType BySJout --outReadsUnmapped Fastx --outFilterScoreMin 10 --outSAMattrRGline $RG --alignEndsType EndToEnd
The unmapped reads from the first STAR alignments were then mapped to mm10 using STAR version 2.5.2b using parameters: --outSAMunmapped Within --outFilterMultimapNmax 30 --outFilterMultimapScoreRange 1 --outSAMattributes All --outStd BAM_Unsorted --outSAMtype BAM Unsorted --outFilterType BySJout --outReadsUnmapped Fastx --outFilterScoreMin 10 --alignEndsType EndToEnd
Peaks were called on mm10 alignments using MACS version 1.4.2 using parameters: -t -c --name --format="BAM" -g mm --tsize=75
Genome_build: GRCm38 p4 Release M11
Supplementary_files_format_and_content: Tab-delimited Excel file containing the peaks identified for each sample by MACS
