Amersham Biosciences has introduced the Ettan DIGE system for separating proteins using 2D DIGE, which was previously only available through an early access program, the company said last week. With its patented cyanine dye technology, the Ettan DIGE system allows researchers to compare protein expression levels from up to three samples on the same gel. The Ettan DIGE system comes with Amersham’s proprietary cyanine dye chemistry, CyDye DIGE fluors (exclusively licensed to Amersham Biosciences from Carnegie Mellon University), the Typhoon variable-mode gel imager, and DeCyder differential analysis software.
Varian has released its LC/NMR/MS system for separating, identifying, and quantifying metabolites, the Palo Alto, Calif.-based company said. Varian is offering the combined product with either a triple quadrupole or single quadrupole mass spectrometer, and NMR spectrometers ranging from 400 MHz to 800 MHz. The LC/NMR/MS systems will be available for delivery in September 2002.
Alessandro Pedretti and Giulio Vistoli of the Medicinal Chemistry Institute of Milan University have released the final version of VEGA1.4.0, a program to convert, manage, and visualize 3D protein structure for several computing platforms. The final release offers a number of new features, including a MDL Mol file loader, improved IFF file format, extended command line interface for language scripting, and a return code handler. The release also contains a new plugin architecture that allows users to write their own source code to add custom applications to the VEGA platform. For more details see http://users.unimi.it/~ddl.
