New Products: 4700 Proteomics Analyzer, PreBIND, Expressway

Premium

After a year of beta testing at Celera, Oxford GlycoSciences, the University of Geneva, and the University of California, San Francisco, Applied Biosystems last week announced the commercial launch of its MALDI-TOF/TOF mass spectrometry system, called the 4700 Proteomics Analyzer.

The system can identify and characterize protein samples at rates of as much as 1000 samples per hour, ABI claimed in a release. The instrument was developed at ABI’s Proteomics Research Center in Framingham, Mass.

ABI said it has received orders from several undisclosed large pharma companies and research institutions in the US, Europe, and Japan.

 

MDS Proteomics has made publicly available its PreBIND search engine used to systematically compile a set of published protein-protein interactions, MDS Proteomics chief scientific officer Mike Moran said last week.

PreBIND is a support vector machine and natural language-processing-based algorithm designed to identify abstracts that describe protein-protein interactions. It is publicly accessible at bind.ca.

 

Invitrogen has commercially launch-ed its Expressway in vitro protein expression system, the San Diego-based company said last week.

Scientists working with PCR amplified genes, open reading frame genes, or genes cloned into vectors can use the Expressway system to produce up to 50 micrograms of protein in two hours, the company said in a statement.
