Sample GSM2808750 Query DataSets for GSM2808750
Status Public on Dec 27, 2018
Title ETO2_Chip_input1
Sample type SRA
 
Source name FLK1+mesoderm
Organism Mus musculus
Characteristics cell type: ES cell-derived embryoid bodies
strain: C57Bl/6 X Sv129
ebs stage: day 4
antibody: none
Extracted molecule genomic DNA
Extraction protocol Complexes were eluted from beads in a thermomixer at 65 degres for 15 min and the eluates and reserved inputs were reverse cross-linked overnight at 65C. The samples were then treated with RNaseA, proteinase K and phenol/chloroform purified.
ChIP samples were submitted to library preparation using NEBNext Ultra DNA Library prep kit for Illumina (NEB 7370) and multiplexing barcodes (NEB E7500) following Illumina’s instructions.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model NextSeq 550
 
Data processing Base calling performed on illumina 1.9 platform
Chipseq reads were aligned to the mm9 genome reference. Data were analysed using in-house pipeline that automatically assesses the quality of data, trims adaptors, merges short reads, maps reads to the reference genome, and filters data for duplicates: http://userweb.molbiol.ox.ac.uk/public/telenius/PipeSite.html
mapping : bowtie -m 1 --maxIns 350 --lanes 4
for un-mapping reads : trim_galore -- length 10, --noFlash
removing duplicates : samtools rmdup
no ploidy region (bedtools pairtobed )
reconstructing sequenced fragments from R1+R2 read pairs ( bedtools bedpe | cut -f 1,2,6) - for visualisation
pileup of fragments (bedtools genomecov -counts)
generating bigwig tracks (ucsctools bedGraphToBigWig)
peak calling were performed using Macs2 v2.0.10 with the following parameters -B -q 0.05 --to-large
Genome_build: mm9
Supplementary_files_format_and_content: narrowPeak files were generated with macs2
Supplementary_files_format_and_content: bed file: tab delimited text file containing peakcalling union of replicate 1 and 2
