Vincent J. Coates
Proteomics/Mass Spectrometry Laboratory (P/MSL)

The UCB Proteomics/Mass Spectrometry Laboratory (P/MSL) was founded in 2004 as part of UCB’s Cancer Research Laboratory.  In 2007, we became the Vincent J. Coates Proteomics Laboratory, affiliated with QB3, in order to provide improved access to Proteomics services.  We now occupy a spacious laboratory in Stanley Hall with a “wet” biochemistry area for protein sample preparation and room for expansion of our array of mass spectrometers.

The P/MSL provides proteomics services principally through mass spectrometry.  Our tools are ion trap mass spectrometers equipped for LC-nanoelectrospray experiments. Currently we have two Thermo LTQ XL linear ion trap mass spectrometers, one of which is equipped for ETD fragmentation. A Thermo Discovery Orbitrap mass spectrometer is available for proteomics applications that demand high mass accuracy.

We specialize in the identification of proteins from complex samples using MudPIT chromatography as developed in the Yates lab.  We can locate post-translational modifications using either CID or ETD peptide fragmentation. Modification analysis is available even in complex samples. We can also perform relative quantitation in labeled samples employing SILAC or similar techniques. Many other  types of analysis are possible. Please check our services offered to see details about analyses we perform routinely.

If you are looking for small molecule mass spectrometry, visit the webpage of our friends the Chemistry Mass Spectrometry Facility.

New Lower Rates
Due to increased sample volume, we have been able to lower our rates. We also now offer high resolution analysis for SILAC relative quantitation. Please look under the rates tab to see what your analysis will now cost. More >
