Sample GSM4051537 Query DataSets for GSM4051537
Status Public on Mar 23, 2021
Title Otx_braLan_15hpf_4C-seq
Sample type SRA
 
Source name 15 hpf amphioxus embryos
Organism Branchiostoma lanceolatum
Characteristics 4c-seq bait: Otx promoter
tissue: whole embryos
Stage: 15 hpf
Growth protocol Embryos were cultivated at 19°C in filtered seawater until desired developmental stage
Extracted molecule genomic DNA
Extraction protocol Chromatin was extracted from single cells preparations from different samples. DNA was digested with DpnII and ligated. Then sample was de-crosslinked, digested with Csp6I and ligated again.
Primers with Illumina adaptors were used to amplify the library. Different samples were multiplexed for sequencing.
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina HiSeq 2000
 
Description 4C-seq experiments performed using as bait the specified promoter
Data processing Library strategy: 4C-Seq
Demultiplexing: Different samples were demultiplexed using the primer sequences
Mapping: Reads were mapped to the Branchiostoma lanceolatum (Bl71nemr assembly) or Danio rerio (danRer7 assembly) genomes using Bowtie software (http://bowtie-bio.sourceforge.net). Only uniquely mapped reads were kept.
Filtering: Only those reads that mapped withing fragments with a DpnII at one end and a Csp6I at the other end were kept.
Data visualization: Data were uploaded to UCSC Browser for visualization.
Genome_build: danRer7/Bl71nemr(http://amphiencode.github.io/Data/)
