DNA Mapping Arrays
Affymetrix provides a broad range of expression, whole genome, and custom arrays. Please visit http://www.affymetrix.com/products/arrays/index.affx for a complete, up-to-date listing of arrays available.
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
- 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, 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.
Mapping 100K Array and Assay Set
The GeneChip® Human Mapping 100K Set is comprised of a set of two arrays that provide high resolution copy number analysis. With a mean marker distance of 26 kb, the Mapping 100K Set provides high genomic coverage, giving researchers more power to detect changes in chromosomal copy number. The Mapping 100K Set can provide both copy number and allele specific information, allowing researchers to discover copy neutral changes.
The GeneChip Mapping 100K Set has also been used for other applications, including population genetics, linkage disequilibrium analysis, and whole-genome association studies.
Mapping 10K 2.0 Array and Assay Set
The GeneChip® Human Mapping 10K Array Xba 142 2.0 is a SNP genotyping tool for investigating the genetics of complex human disease. More power, less PCR and less DNA: 10,000 SNPs, One Primer, One Array.
