Sample GSM1874151 Query DataSets for GSM1874151
Status Public on Oct 01, 2015
Title Placenta [14S0026442]
Sample type genomic
 
Channel 1
Source name Induced abortion_Placental tissue
Organism Homo sapiens
Characteristics sample origin: Induced abortion
clinical indication: Ultrasound abnormality: gastroschisis, cleft lip, syndactylia, ectodactyle; the first fetus was diagnosed with gastroschisis and inevitable abortion for the second fetus
tissue: Placental tissue
Treatment protocol Samples were untreated
Growth protocol Uncultured samples of chorionic villus sampling, amniotic fluid, placental tissue and blood were used for direct DNA extraction
Extracted molecule genomic DNA
Extraction protocol Genomic DNA extraction done by Qiagen DNeasy® Blood & Tissue Kit following manufacturer's instructions
Label Cy5
Label protocol Three costumized aCGH approach have different procedure for DNA fragmentation and labelling; Agilent-022023:1 µg of Genomic DNA samples were fragmented. The fragmented DNA sample were labeled with Cy5 and the corresponding fragmented reference controls were labeled Cy3 using Agilent SureTag DNA Labeling Kit. Agilent-068656:300 ng of Genomic DNA samples were heat fragmented. The fragmented DNA samples were labeled with Cy5 and the corresponding fragmented reference controls were labeled Cy3 using Agilent SureTag DNA Labeling Kit. Agilent-035130:300 ng of Genomic DNA samples were enzyme digested. The digested DNA samples were labeled with Cy5 and the corresponding fragmented reference controls were labeled Cy3 using Agilent SureTag DNA Labeling Kit.
 
Channel 2
Source name control_blood
Organism Homo sapiens
Characteristics sample origin: Healthy Chinese adult control
tissue: blood
Treatment protocol Samples were untreated
Growth protocol Uncultured samples of chorionic villus sampling, amniotic fluid, placental tissue and blood were used for direct DNA extraction
Extracted molecule genomic DNA
Extraction protocol Genomic DNA extraction done by Qiagen DNeasy® Blood & Tissue Kit following manufacturer's instructions
Label Cy3
Label protocol Three costumized aCGH approach have different procedure for DNA fragmentation and labelling; Agilent-022023:1 µg of Genomic DNA samples were fragmented. The fragmented DNA sample were labeled with Cy5 and the corresponding fragmented reference controls were labeled Cy3 using Agilent SureTag DNA Labeling Kit. Agilent-068656:300 ng of Genomic DNA samples were heat fragmented. The fragmented DNA samples were labeled with Cy5 and the corresponding fragmented reference controls were labeled Cy3 using Agilent SureTag DNA Labeling Kit. Agilent-035130:300 ng of Genomic DNA samples were enzyme digested. The digested DNA samples were labeled with Cy5 and the corresponding fragmented reference controls were labeled Cy3 using Agilent SureTag DNA Labeling Kit.
 
 
Hybridization protocol After clean up and QC check, Cy3 and Cy5 labeled DNA samples were mixed together with Cot-1 DNA, blocking agent and hybridization buffer using Agilent Oligo aCGH/ChIP-on-Chip Hybridization kit according to manufacturer's protocol. Samples were hybridized on array for 24 hours at 65oC. After hybridization, slides were washed sequential
Scan protocol Scanned on an Agilent G2505C scanner.
Data processing Agilent Feature Extraction Software (v 11.5.1.1) was used for background subtraction
Dye was normalized automatically according to the dye norm list in eArray generating the normalized log10 ratio (Cy5/Cy3), representing test/reference
