No culture but direct isolation from peripheral blood
Extracted molecule
genomic DNA
Extraction protocol
Genomic DNA was isloated with a Chemagen/Hamilton magnetic bead DNA isolation robot
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.
Description
Hybridized to 250K_Nsp
Data processing
The array image was acquired using Affymetrix GeneChip® Operating Software (GCOS version 1.4). Copy number values for individual SNPs were extracted and converted from CEL files into signal intensities using GTYPE 4.0 and Copy Number Analyzer for Affymetrix GeneChip mapping (CNAGT 2.0) software. The inferred copy number states were derived from a Hidden Markov Model (HMM) based algorithm implemented in CNAG2.0. Regions of homozygosity (LCSH/LOH) were determined with a likelihood based algorithm implemented in CNAG2.0. Genotype Call (SNP call): AA, AB, BB, NC, and NoCall; 'Signal' = Summarized signal
