Sample GSM2793697

Query DataSets for GSM2793697

Status

Public on Mar 16, 2018

Title

E7-0-P-IP-K27me3

Sample type

SRA

Source name

K27me3 microChIP

Organism

Mus musculus

Characteristics

strain: ICR
developmental stage: 7.0 dpc
tissue: embryo
chip antibody: H3K27me3 (merck millipore, cat. 07-449, lot 2275589)

Growth protocol

Embryo were collected from pregnant mice at 6.5, 7.0 and 7.5 dpc

Extracted molecule

genomic DNA

Extraction protocol

RNA from embryo samples were extracted by 5M GuSCN (Invitrogen, # 20012-043), then RNA was precipitated by ethanol with the help of RNA carrier; Genomic DNA acquired from ChIP assay (H3K27me3, merck millipore, catlog number: 07-449, lot number: 2275589) of embryo samples were separated and extracted by microChIP. Genomic DNA acquired from embryos were separated and extracted followed by bisulfite sequencing
Libraries of genomic DNA were construted by using NEBNext Ultra DNA Library Prep Kit for Illumina (NEB #7370L); libraries of genomic DNA were construted by using NEBNext Ultra DNA Library Prep Kit for Illumina (NEB #7370L); libraries of single cell based bisulfite seq were constructed according to the protocol described in (H Guo et al, Nature Protocol 10(5):645-59).

Library strategy

ChIP-Seq

Library source

genomic

Library selection

ChIP

Instrument model

Illumina HiSeq 2500

Data processing

Illumina CASAVA version 1.8 were used to the basecalling.
Sequencing adapters, low quality sequences and amplification primers were trimmed from the raw sequencing reads.
For RNA-seq data, trimmed clean reads were aligned to mouse reference genome (mm10) using TopHat (v2.0.9) with the default parameters
For Bisulfite seq, the trimmed reads were mapped to mm10 mouse genome following our modified bisulfite sequencing pipeline.(H Guo et al, Nature Protocol 10(5):645-59)
For the ChIP-seq data, the trimmed reads were mapped to the mouse genome (mm10 assembly) using BWA sligner (version 0.7.5a-r405) with the options "-I 15 -q 10 -t 4"
Genome_build: mm10
Supplementary_files_format_and_content: the bigwig files for ChIP-seq include the H3K27me3 modification in each sample with merged data from two biological replicates.
