Tools could transform proteomics research

Published: 1-Apr-2004


A new suite of proteomics tools has been developed by Thermo Electron Corporation. The Finnigan ProteomeX LTQ

proteomics workstation is based on the Finnigan LTQ mass spectrometer and uses the new, high performance proteomics autosampler, the Finnigan Micro AS and optimised column and method combinations for proteomics applications.

The ProteomeX enables the researcher to perform High Throughput protein ID, maximum sequence coverage, phosphorylation site mapping, and multidimensional protein identification technology (MudPIT) with an intuitive, automated system operation.

Thermo is also introducing the Finnigan vMALDI ion source an integrated intermediate-vacuum MALDI source for the Finnigan LTQ Linear Ion Trap. Its ion source combines the speed of MALDI with the sensitivity of the Finnigan LTQ to create SEQUEST-searchable MS/MS spectra for unambiguous protein assignments. Fast, data-dependent MS/MS analysis of protein digests permits the researcher to perform confident, high throughput protein identification in a single LC/MS experiment, the company says.
