Sample GSM325774 Query DataSets for GSM325774
Status Public on Mar 09, 2010
Title MyoD ChIP-chip on Ciona intestinalis embryo (early-mid gastrula) Sample 1, Array 2
Sample type genomic
 
Channel 1
Source name Whole Cell Extract (WCE) DNA
Organism Ciona intestinalis
Characteristics Whole Cell Extract (WCE) DNA
Biomaterial provider The national bio-resource project for Ciona intestinalis (http://www.nbrp.jp/)
Treatment protocol Approximately 3 kb of the MyoD promoter and the coding region of MyoD were cloned into pDONR P4-P1R and pDONR221 (Invitrogen), respectively. cDNA encoding GFP was cloned into pDONR P2R-P3. Recombination of these three plasmids with Multisite Gateway technology (Invitrogen) resulted in a construct encoding GFP-tagged MyoD.
Fertilized eggs were electroporated with this DNA construct.
Growth protocol C. intestinalis adults were obtained from the national bio-resource project for Ciona intestinalis 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 embryos were fixed with 1% formaldehyde for 15 min. Chromatin was sonicated to obtain DNA fragments with an average of size of 1kb.
After reversal of the fixation, the WCE 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).
 
Channel 2
Source name GFP-tagged MyoD ChIP in Ciona intestinalis embryo (early-mid Gastrula)
Organism Ciona intestinalis
Characteristics GFP-tagged MyoD ChIP in Ciona intestinalis embryo (early-mid Gastrula)

Extracted molecule genomic DNA
Extraction protocol The embryos 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 GFP (Invitrogen). After reversal of the fixation, the immunoprecipitated DNA were amplified by LM-PCR.
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 MyoD ChIP-chip on Ciona intestinalis embryo (early-mid gastrula) Sample 1, Array 2
GFP-tagged MyoD ChIP-chip in Whole Genome region in Ciona intestinalis embryo (early-mid gastrula) using polyclonal anti-GFP antibody (Invitrogen)
Data processing The resulting fluorescence intensity for each spot was quantified using Agilent Feature Extraction Software ver. 9.1 (Agilent Technologies).
value = log2(Signal for Cy5 / Signal for Cy3)
