Roche NimbleGen last month launched its Human CGH 12x135K Whole-Genome Tiling version 2.0 array for the analysis of DNA copy number variation.
The array allows the analysis of 12 independent sample pairs on a single microarray slide, each with 135,000 oligonucleotide probes. The chips are manufactured on Roche NimbleGen's new 2.1-million feature HD2 platform. NimbleGen previously made available 385K and 4x72K arrays for CGH.
To support the new CGH arrays, NimbleGen also launched NimbleScan version 2.5, software that includes an experimental metrics report and enhanced analysis features for the arrays.
