Sample GSM2549944 Query DataSets for GSM2549944
Status Public on Jun 11, 2017
Title Tbx16_input
Sample type SRA
 
Source name whole zebrafish embryos
Organism Danio rerio
Characteristics strain: AB
Stage: 75-85% epiboly
Treatment protocol Embryos fixed in 1.85% formaldehyde for 15 mins prior to chromatin extraction
Growth protocol Embryos grown in E3 embryo medium at 28.5 degrees celcius and heat-shocket for one hour at 37 degrees celcius prior to fixation
Extracted molecule genomic DNA
Extraction protocol Sequential cytoplasmic and nuclear lysis, followed by sonication and centrifugal clarification from was used to obtain chromatin of appropriate fragment size. Desired protein-DNA complexes were isolated using antibody.
Libraries were prepared according to Illumina's instructions accompanying the DNA Sample Kit (Part# 0801-0303). Briefly, DNA was end-repaired using a combination of T4 DNA polymerase, E. coli DNA Pol I large fragment (Klenow polymerase) and T4 polynucleotide kinase. The blunt, phosphorylated ends were treated with Klenow fragment (32 to 52 exo minus) and dATP to yield a protruding 3- 'A' base for ligation of Illumina's adapters which have a single 'T' base overhang at the 3’ end. After adapter ligation DNA was PCR amplified with Illumina primers for 15 cycles and library fragments of ~250 bp (insert plus adaptor and PCR primer sequences) were band isolated from an agarose gel. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer following the manufacturer's protocols.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina Genome Analyzer IIx
 
Data processing Reads were mapped to the Zv9 version of the genome with Bowtie using the following parameters: -y -m2 -k2 --best.
Peaks were called for each ChIP sample relative to their paired input sample using MACS with the following parameters: --gsize 1.3e+9 –mfold 10 -pval 1e-4 for Tbx16.
Peak coordinates common to both ChIP replicates were identified for further analysis using custom Perl scripts
Genome_build: Zv9
Supplementary_files_format_and_content: Wig files for track visualization of ChIP and input data.
