Tsui-Fen Chou РFaculty Director

The Proteome Exploration Laboratory provides both scientific and technical expertise and state-of-the-art high performance and ultrahigh performance liquid chromatography and tandem mass spectrometric instrumentation.

The lab is currently equipped with an Agilent 1100 MSD instrument, two Thermo EASY-nLC Orbitrap instruments (Classic and Elite), and an Thermo EASY-nLC LTQFT linear ion trap with electron capture dissociation (ECD) and infrared multiple photon dissociation (IRMPD) capabilities and an AB Sciex nanoLC QTRAP. Ancillary instrumentation includes a Nanomate direct infusion device, additional HPLC systems, capillary puller etc. Our bioinformatics suite contains a Mascot server, MaxQuant, the TransProteomics Pipeline, Scaffold, Sequest, ROCCIT and other in-house developed software tools that are constantly being developed.

A major research focus within the laboratory is method development for comparative quantitative proteome analysis, including the comprehensive analysis of posttranslational modifications.

We collaborate with California Institute of Technology scientists from various backgrounds. By nature, the level of collaboration varies from project to project. To achieve best results, we encourage investigators to contact us before a project is started.
