Genome-Wide Human SNP Array 6.0

The new Affymetrix ® Genome-Wide Human SNP Array 6.0 features more than 1.8 million markers for genetic variation, including more than 906,600 single nucleotide polymorphisms (SNPs) and more than 946,000 probes for the detection of copy number variation.

  • Unbiased selection of 482,000 SNPs comprised of historical SNPs from the SNP Array 5.0 and 500K Mapping Array Set
  • Selection of additional 424,000 SNPs, including Tag SNPs, SNPs from chromosomes X and Y, Mitochondrial SNPs, New SNPs added to the dbSNP database, and SNPs in recombination hotspots
  • More than 946,000 copy number probes, including 202,000 probes targeting 5,677 known CNV regions from the Toronto Database of Genomic Variants; Regions resolve into 3,182 distinct non-overlapping segments; on average 61 probes per region; 744,000 probes, evenly spaced along the genome.

Genome-Wide Human SNP Array 5.0

Released in early 2007, the Human SNP Array 5.0 represents the latest evolution of SNP mapping technology. The new array contains all SNPs from the previous 500K Array Set plus an additional 420,000 non-polymorphic probes that can measure other genetic differences, such as copy number variation. All of this means more powerful studies with reduced processing time.

Mapping 500K Array and Assay Set

The GeneChip ® Mapping Assay for the Human Mapping 500K Array Set builds on the proven and simple approach for reducing complexity of the genome that is employed by the GeneChip ® Human Mapping 10K Array and the GeneChip ® Mapping 100K Set. With over five times the SNP content of the 100K Set and over twice the genetic power, the Mapping 500K Array Set enables truly high-powered, whole genome association.
