Illumina this week launched its HumanOmniExpress+ Custom BeadChip. The new array is an enhancement to its OmniExpress BeadChip that allows for the addition of up to 200,000 custom variants to enable customers to survey more than 900,000 variants per sample.

Using the iScan System and an eight-sample array format, Illumina said customers who use the OmniExpress+ can process more than 900 samples per week.


BioDiscovery this week launched Nexus Expression version 2 for gene expression analysis. Nexus Expression provides a software interface for using gene expression results to associate sample attributes with gene annotations and biological processes.

New features in version 2 enable users to load data with a one-click tool and to find relevant biological information, the company said. The software also includes a library of pathways and gene sets to identify the biological implications of differential gene regulation. Another new feature facilitates data loading from array manufacturers' software with a new plug-in for Illumina's software as well as support for CEL files and annotation files from Affymetrix arrays.
