Updated CGH microrray software can process 100+ samples

Agilent Technologies Inc. presents Agilent DNA Analytics 4.0 software for visually exploring, detecting and analyzing patterns in microarray data. Among the additions in the new release include the ability to analyze more than 100 samples per experiment, a free genomic browser and copy number variation (CNV) analysis capability. These features join existing chromatin immunoprecipitation-on-chip (ChIP-on-chip), array-based comparative genomic hybridization (aCGH), and gene expression analytics capabilities.

"The speed of processing is amazing; it makes working with 244K chips much more interactive," said early-access user Michael Bittner of Translational Genomics Research Institute. "Changes to analytical conditions no longer produce 20- to 60-minute waits, and the graphics updates generally occur in seconds."

For large-scale experiments, Agilent DNA Analytics 4.0 can process more than 100 microarrays (244K), helping users easily compare data and visualize patterns. The package also now includes a free genomic browser that enables researchers to share data and results.

Agilent also announced that it has updated its eArray online design tool for creating custom

microarrays by expanding the CGH probe database from 8.4 to more than 24.5 million probes. This advance in microarray probe density and the addition of search capabilities specific to this content provide a more comprehensive coverage of genome, including CNVs.
