Sample GSM2704271 Query DataSets for GSM2704271
Status Public on Dec 05, 2017
Title STEM-seq E7.5Ect rep3
Sample type SRA
 
Source name Postimplantation embryo
Organism Mus musculus
Characteristics strain: C57BL/6N x DBA/2N
developmental stage: E7.5
tissue: Ectoderm
Treatment protocol C57BL/6N female mice were induced for superovulation by injections of 5 IU of pregnant mare’s serum gonadotrophin and 5 IU of human chorionic gonadotrophin (44-48 hours apart) and mated to DBA/2N males.
Extracted molecule genomic DNA
Extraction protocol Embryos were washed with PBS and incubated in lysis buffer. STEM-seq libraries were constructed following the protocol described in this study (Zhang et al., Nature Genetics, 2017).
 
Library strategy Bisulfite-Seq
Library source genomic
Library selection RANDOM
Instrument model Illumina HiSeq 2500
 
Description Processed data file: stage.mCG.gz in STEM-seq-methylC_mCG.tar.
Data processing Base calls were performed using CASAVA version 1.8. Early embryo STEM-seq reads were aligned to the mm9 genome using BSseeker2.0.8. Replicates of same stage were pooled together and methylation values in wiggle files were computed for each single base. ES cell STEM-seq and MethylC-seq reads were aligned to the mm9 genome using BSseeker2.0.8. Replicates of same stage were pooled together and methylation values in wiggle files were computed by the number of reads falling into 1,000bp bin in the genome.
Genome_build: mm9.
Supplementary_files_format_and_content: The bedgraph files counted the number of reads falling on each base or 1,000bp bin in the genome.
