Proteomics Core

Metadata Updated: March 8, 2017

Proteomics Core is the central resource for mass spectrometry based proteomics within the NHLBI. The Core staff help collaborators design proteomics experiments in a way that are compatible with mass spectrometry and to modify protocols if needed to ensure they will provide high quality data. An important aspect of the Core[HTML_REMOVED]s mission is to teach users new methods, techniques and instruments. The Core also continually innovates on existing technologies.Our workflows for relative protein quantitation are based on DIGE, label-free and iTRAQ approaches. We can also help investigators identify and quantify protein posttranslational modifications, including phosphorylation, nitrosylation, acetylation, ubiquitination, etc. We provide training in proper sample preparation and lead the researchers through mass spectrometric analysis to data searching and interpretation. Users have access to a variety of proteomics software platforms (Mascot, Sequest, Proteome Discoverer, Scaffold, Protein Pilot) for re-searching the data or viewing the results.In addition to helping the NHLBI investigators, we develop new approaches for characterization of posttranslational modifications and absolute protein quantitation.The NHLBI Proteomics Core was a recipient of the 2012 NHLBI Orloff Award for outstanding research support.

Recent studies and method development include:Acetylation on lysine (developing workflows for identification and occupancy measurements)Nitrosylation on cysteine (developing workflows for identification and occupancy measurements)Ubiquitination and SUMOylation (workflows for identification and quantitation)Development of [HTML_REMOVED]mito-panel[HTML_REMOVED] - using targeted analysis on Velos to follow specific mitochondrial proteinsDepletion of the most abundant serum proteins to study the protein differences in patients[HTML_REMOVED] samplesAbsolute protein quantitation using SRM on Velos instrumentsDevelopment of iTRAQ quantitation software (Quari) and measurement of and correction for isolation purity in iTRAQSeparation of peptides and phosphopeptide enrichment using IEF or OFF-Gel SystemInstrumentsMass spectrometers Thermo Orbitrap Velos Elite 1
