GeneData, headquartered in Basel, Switzerland, has released version 3.1 of its GeneData Expressionist Suite for microarray analysis. The new version includes improvements in data quality control, data mining, and the database modules, the company said.
A major addition to this new version is GeneClassifier, a system that allows users to import gene annotations and to integrate species-specific content into the analysis. The user can also create gene classifications — for example, functional classifications such as “translation, ribosomal” and “lipid metabolism.” The system also includes principal component analysis, a present-absent search feature, and the capability to perform searches whose parameters are defined by the user.
GeneData’s system is designed to work with Affymetrix LIMS and MAS systems, uploading data automatically from these software packages and running it through a proprietary quality control process designed specifically for Affymetrix data. The system also links to Affymetrix’s NetAffx web portal for retrieval of information about genes, and is sold both by GeneData directly, and Affymetrix, with which the company has a non exclusive co-marketing agreement.
Beckman Coulter has introduced its Tube Strip Rotor for its Microfuge 22R microcentrifuge. The rotor, according to the company, is designed to minimize condensation from PCR reactions using quick spins. It can also be used for post-reaction cleanup. The rotor, which includes an aerosol-tight lid and is autoclavable at 121 degrees Celsius, can accommodate up to 12 strips of eight 200 nanoliter tubes.
