Oxford Gene Technology (OGT) has introduced the CytoSure™ ISCA UPD 4 x 180k array. This offers the ability, for the first time, to simultaneously detect DNA copy number variation (CNV) using OGT’s ISCA consortium endorsed 4 x 180k aCGH array, along with whole chromosome uniparental disomy (UPD) using SNP probes, on a single array.
The array format and ease-of-use data interpretation via the complimentary CytoSure Interpret Software, combine to make the CytoSure ISCA UPD array a choice for the next stage in cytogenetic research.
OGT’s UPD detection capability (patent pending) has been enabled by multiple rounds of SNP probe selection and validation, targeting over 6000 SNPs with evenly distributed probes, resulting in highly informative content that allows confident detection of whole chromosome UPD.
Furthermore, the combined ISCA-UPD array has been developed to ensure near identical labelling and hybridization conditions to standard aCGH. In addition, the aCGH protocol is largely unaltered and any reference DNA can be used.
The latest version of OGT’s CytoSure Interpret Software provides simple data analysis, with clear identification of regions with a loss of heterozygosity (LOH) and data processing tools to investigate these further. As a result of this array design and data analysis capability, segmental as well as whole chromosome UPD can be detected using the CytoSure ISCA UPD array.
James Clough, Vice President Clinical and Genomic Solutions at OGT commented: “We have carefully implemented robust UPD detection capabilities onto our CytoSure ISCA 4 x 180k arrays, whilst avoiding wholesale changes to the protocol. Importantly, we have also made the interpretation of this additional data extremely intuitive via our CytoSure Interpret Software. As a result, our customers can now confidently detect both DNA copy number variation and whole chromosomal uniparental disomy using a single array.”
