Sample GSM1821491 Query DataSets for GSM1821491
Status Public on Apr 22, 2016
Title Gata.a ChIP-chip in Ciona intestinalis embryo (16-cell stage) Sample 1
Sample type genomic
 
Channel 1
Source name Whole Cell Extract (WCE) DNA
Organism Ciona intestinalis
Characteristics Stage: 16-cell stage
tissue: whole embryo
Treatment protocol Ciona intestinalis embryos were cultured until 16-cell stage without any specific treatment.
Growth protocol Ciona intestinalis adults were obtained from the National BioResource Project Ciona intestinalis Organization and were maintained under constant light to induce oocyte maturation. Eggs and sperm were obtained surgically from the gonoduct. Following insemination, eggs were washed and maintained in seawater at 18˚C in Millipore-filtered seawater containing 50ug/ml streptomycin sulfate.
Extracted molecule genomic DNA
Extraction protocol The embryo were fixed with 1% formaldehyde for 15 min. Chromatin was sonicated to obtain DNA fragments with an average of size of 1kb. The DNA fragments were enriched by immunoprecipitation with an polyclonal antibody specific for Gata.a, Tcf7 and Zic-r.a, respectively. After reversal of the fixation, the immunoprecipitated DNA were amplified by LM-PCR.
Label Cy3
Label protocol Amplified DNA was directly labeled by random-primed, Klenow-based extension protocol that is used with CGH Labeling kit (Invitrogen).

Label Cy5
Label protocol Amplified DNA was directly labeled by random-primed, Klenow-based extension protocol that is used with CGH Labeling kit (Invitrogen).
 
 
Hybridization protocol Hybridization and washing protocols were according to the manufacturer’s instructions (Agilent Technologies).
Scan protocol The microarrays were scanned with an Agilent G2565BA Microarray Scanner (Agilent Technologies).
Description Gata.a ChIP-chip sample 1. WT Ciona intestinalis embryo, untreated, harbested, immunoprecipitated by polyclonal anti-Gata.a antibody
Data processing The resulting fluorescence intensity for each spot was quantified using Agilent Feature Extraction Software ver. 9.1 (Agilent Technologies).
