Sample GSM1274394 Query DataSets for GSM1274394
Status Public on Feb 13, 2015
Title MRE_24hpf
Sample type SRA
 
Source name embryo
Organism Danio rerio
Characteristics developmental stage: 24hpf
hours post fertilization: 24
strain: sjA
Extracted molecule genomic DNA
Extraction protocol Wild-type embryos were obtained through in vitro fertilization, grown in 28.5 °C egg water to develop and harvested at the desired stages. Chorions were removed with pronase and yolk was removed with ice-cold deyolking buffer (55 mM NaCl, 1.8mM KCl, 1.25 mM NaHCO3). Embryos were snap-frozen in liquid nitrogen and stored at -80 °C until time of use. The genomic DNA was isolated by incubating embryos in genomic DNA extraction uffer (50 mM Tris, 1 mM EDTA, 0.5 % SDS, 1 mg/mL Proteinase K) followed by phenol-chloroform extraction.
5 parallel digests (HpaII, Hin6I, SsiI, BstUI and HpyCH4IV; New England Biolabs) were performed, each with 200 ng of DNA. Digested DNA was combined, size-selected, end-processed, and ligated to single-end adapters. After the second size-selection, DNA was amplified by 15 cycles of PCR and size-selected by agarose gel electrophoresis.
 
Library strategy MRE-Seq
Library source genomic
Library selection Restriction Digest
Instrument model Illumina HiSeq 2000
 
Data processing Base-calls performed using CASAVA.
Raw sequencing reads were aligned to the danRer7 genome assembly using novoalign (V2.08.02) with the following parameter: -o SAM -r random -a -H.
The aligned reads were further processed using homemade perl scripts. These include bed sorting, MRE site filtering and calculating normalized score.
