The ProteomeX Workstation is a multidimensional liquid chromatography/mass spectrometry (LC/MS) package that combines three successful Thermo Finnigan components: an LCQ™ Deca XP ion trap mass spectrometer, Surveyor® HPLC, and new BioWorks™ 3.0 software, including TurboSEQUEST®. "This is one-stop shopping for proteomics," says Ken Miller, product marketing manager for proteomics.
The ProteomeX's multidimensional LC/MS allows a researcher to analyze proteins in complex samples, such as bacteria, plasma, or a human cell line. After protease digestion, the peptides in the sample are separated by capillary cation exchange followed by high-resolution reversed-phase LC. The mass spectrometer then detects and sequences the separated peptides. Finally, protein databases are queried with the observed sequences to determine the proteins from which the peptides were derived. Researchers can use the ProteomeX system for other proteomics applications, including high-throughput methods using tandem HPLC columns, in which samples can be loaded on the first column while eluting off the ...
