The Infinium CytoSNP-850K BeadChip is the first SNP-based human microarray to leverage the latest input from the international community for cytogenomics studies.
The gene list was defined based on content from the International Collaboration for Clinical Genomics (ICCG)1 and the Cancer Genomics Consortium (CGC)2, providing a thorough view of cytogenomic activity.
The use of long 50-mer probes with high specificity to the SNP target increases sensitivity for low-level mosaics3 and offers high resolution for copy-neutral loss of heterozygosity (LOH). High 15× bead redundancy increases the signal-to-noise ratio for making accurate CNV and absence of heterozygosity (AOH) calls across the genome.
