Sample GSM7233873 Query DataSets for GSM7233873
Status Public on Apr 30, 2023
Title amniotic fluid P167-750knsp
Sample type genomic
Source name amniotic fluid P167
Organism Homo sapiens
Characteristics cell type: amniotic fluid
indications of invasive prenatal diagnosis: isolated increased NT
offspring gender: male
Treatment protocol None
Growth protocol Cell were grown according to standard conditions.
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was extracted from uncultured amniotic fluid, fetal cord blood using a QIAGEN kit (Qiagen, Hilden, Germany) according to the manufacturer's instructions.
Label Biotin
Label protocol As per manufacturer (Affymetrix)
Hybridization protocol DNA was restriction digested, PCR amplified, fragmented, labeled and hybridized to each array according to the manufacturer's instructions.
Scan protocol The Arrays were then washed using Affymetrix fluidics stations, and scanned using the Gene Chip Scanner 3000.
Data processing The array image was acquired using Affymetrix GeneChip® Operating Software (ChAS 4.0). Copy number values for individual SNPs were extracted and converted from CEL files into signal intensities using GTYPE 4.1 and Affymetrix Copy Number Analysis Tool (CNAT 4.0.1) softwares. Genomic Smoothing analysis was performed by using the smoothing window of 0 Mb, and inferred copy number states were derived from a Hidden Markov Model (HMM) based algorithm implemented in CNAT 4.0.1. Circular Binary Segmentation (Ohlsen et al., 2004) was applied using DNAcopy package for R Bioconductor on raw data.
Genotype Call (SNP call): AA, AB, BB, NC, and NoCall; 'Signal' = Summarized signal
