cell type: Lymphocyte Cell Line cell line karyotype: 47,XXX sample type: gDNA
Growth protocol
Four human fibroblast cell lines were cultured as suggested by Coriell Cell Repository
Extracted molecule
genomic DNA
Extraction protocol
Single fibroblast cells underwent alkaline lysis for genomic DNA extraction as described previously (Cui et al., 1989; PNAS 86, 9389-93).
Label
biotin
Label protocol
Fragmented DNA was biotinylated using the manufacturers recommendations (Affymetrix Inc., GeneChip Mapping 500K Assay Manual # 701930)
Hybridization protocol
DNA was digested with the NspI restriction enzyme, ligated to an adapter molecule, PCR amplified, fragmented with DNase I, labeled and hybridized to each array according to the manufacturer's instructions (Affymetrix Inc., GeneChip Mapping 500K Assay Manual # 701930).
Scan protocol
Each array was washed using Affymetrix fluidics station 640, and scanned using the Gene Chip Scanner 7G as recommended (Affymetrix Inc., GeneChip Mapping 500K Assay Manual # 701930).
Description
Hybridized to 250K_Nsp
Data processing
CEL files were processed using GTYPE version 4 (Affymetrix Inc., Genotyping Console 4.0 Manual) using the DM algorithm for genotype calls. Copy number and loss of heterozygosity were calculated from CHP files using CNAT version 4.1 (Affymetrix Inc., Genotyping Console 4.0 Manual) analysis against a reference set of 30 normal females from the HapMap database (www.hapmap.org).
