Single chip for SNPs and CNVs

Affymetrix has officially released its new single-chip SNP 5.0 Array, which allows both single nucleotide polymorphism (SNP) and copy number variation testing on the one chip.

The new array features SNPs from the original two-chip 500K array set, as well as 500,000 additional probes that can measure other genetic differences, such as copy number variation.

The company said the SNP 5.0 Array gives researchers a significant increase in information above the original 500K array set for the same price, while reducing the array processing time.

The SNP 5.0 was developed in collaboration with the Broad Institute of Harvard and the Massachusetts Institute of Technology to better identify and understand the genetic variations associated with complex diseases such as autism, autoimmunity, bipolar disease, cancer, diabetes and heart disease.

Scientists from the Autism Consortium and the Broad Institute are using the SNP 5.0 array to study the genetics of autism.

The SNP Array 5.0 is the most recent addition to Affymetrix' line of genotyping products, including the 10K, 100K and 500K Arrays, which are all based on the Whole-Genome Sampling Assay.

This technology is being used by more than 200 laboratories and has generated data for more than 150 peer-reviewed scientific publications.

Affymetrix continues to work with scientists from the Broad Institute on the design of the higher-density SNP Array 6.0, which is scheduled to launch later this year.

This product is expected to measure more than 1 million SNP and copy number variations across the genome.
