Tecan, SciGene

Tecan this week debuted its QuadChamber for automated processing of four different microarrays simultaneously on one slide, using its HS Pro automated hybridization station.
The QuadChamber was specially developed for use with Agilent’s new 4 x 44,000-feature 4-Plex Gene Expression as well as CGH Microarrays, which consist of four individual, whole-genome microarrays printed on a single glass slide, Tecan said.

According to Tecan, the QuadChamber provides a completely sealed environment around each of the four arrays on Agilent’s 4-Plex slides, with independent channels for wash buffers, independent agitation mechanisms and drying for each of the four areas. 


SciGene this week said it has completed validation studies for a new version of its Little Dipper Processor that will help researchers process Illumina BeadChips used in gene-expression studies.
According to SciGene, the validation of the Little Dipper Processor was accomplished by working together with Illumina and the Baylor Immunology Research Institute in Dallas. The instrument is now pre-programmed with validated protocols and equipped with accessories for automated BeadChip processing.
Illumina will now recommend the Little Dipper Processor to its customers for gene-expression applications, the company said.
