Illumina this week began shipping its new HumanOmni2.5-Quad DNA Analysis BeadChip.
The Omni2.5 includes newly discovered genome-wide common and rare variants from the 1000 Genomes Project selected to maximize its ability to detect new associations, the firm said. The new array is available in a four-sample format composed of approximately 10 million markers per array, and is compatible with an iScan or HiScan system.
Additionally, Illumina said this week that is now shipping its HumanOmni1S-8 BeadChip, which provides a simple upgrade path for current or former users of Illumina's Omni1-Quad or OmniExpress BeadChips by enabling researchers to access new 1000 Genomes Project-derived content without having to purchase the Omni2.5. The 8-sample array contains the majority of new content present on the Omni2.5 and allows for processing of nearly 1,000 samples per week, according to Illumina.
The San Diego life sciences firm has also introduced a new sample-preparation workflow that allows researchers to prepare their DNA samples once and process them across multiple arrays in the Omni family, such as the Omni1 or OmniExpress and Omni1S, or the Omni2.5.
