| Title |
STRAP Embryo eCLIP-2 |
| 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.

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
