Title |
ChIP-Seq 1000-cell-number mESC K27Me3 |
Sample type |
SRA |
|
|
Source name |
Embryonic stem cell
|
Organism |
Mus musculus |
Characteristics |
strain: R1 tissue/cell type: Embryonic stem cell chip antibody: H3K27Me3 chip antibody vendor: Diagenode chip antibody cat. #: C15410069; pAb-069-050
|
Treatment protocol |
Mouse ES cells were cultured without irradiated mouse embryonic fibroblasts (MEFs) in DMEM containing 15% FBS, leukemia inhibiting factor (LIF), penicillin/streptomycin, L-glutamine, β-mercaptoethanol, and non-essential amino acids. After digestion with 0.05% trypsin, counted cells were lysed for STAR ChIP-seq or Smart-seq2.
|
Extracted molecule |
genomic DNA |
Extraction protocol |
mES cells were washed with PBS and incubated in lysis buffer. ChIP-Seq libraries were prepared using TELP developed by PengXu et al. (PMID: 25223787) with slightly modification.

Description |
ChIP-seq of exact 500 mES cells.
|
Data processing |
Basecalls performed using CASAVA version 1.8 ChIP-seq reads were aligned to the mm9 genome using bowtie 2.2.2, replicates of same stage were pooled together and rpkm in wiggle files were counted by the number of reads falling into 100bp bin in the genome RNA-Seq reads were aligned to the mm9 genome assembly using Tophat version 2.0.11, then replicates were merged together, and transcript abundance (FPKM) were calculated based on Refseq annotation using cufflinks version 2.0.2 Genome_build: mm9 Supplementary_files_format_and_content: The bed files include RPKM values in 100bp bins for each ChIP-seq sample. Bed files labeled maternal or paternal contain RPKM values for two parental alleles, allelic reads were normalized to total reads number. Tab-delimited text files include FPKM values RNA-seq sample.
