Roche Nimblegen has announced the launch of comparative genomic hybridisation (CGH) arrays and services for the high-resolution mapping of genomic copy-number differences.
The company's HD2 platform enhances the capability and resolution of CGH whole-genome analysis by providing a single array format containing 2.1 million long oligo probes.
With this increase in probe density, Nimblegen CGH HD2 arrays deliver a median probe spacing of 1.1kb genome wide.
Additional advances in the CGH HD2 array design includes improved probe selection within low-copy repeat regions that were previously inaccessible and broader coverage of the entirety of complex genomes such as human and murine.
The HD2 arrays follow the recent launch of CGH 4x72K arrays, aimed at improving sample throughput for large-scale research projects in which hundreds or thousands of samples are screened for target sets of genomic loci or disease-associated regions.
