PROTEIN AND PROTEOMICS CENTRE (PPC)
A centre for research on proteins, peptides and functional genomics
The Protein and Proteomics Centre (PPC) is a multi-user core facility focused on advanced research in proteins with an emphasis on mass spectrometry. Areas of expertise include biomarker discovery, proteomics, quantitative proteomics, and structural mass spectrometry (Amide Hydrogen/Deuterium Exchange MS and Ion Mobility MS). PPC works closely with academic and industrial partners in biomedical research.
At the Protein and Proteomics Centre, our goal is to provide state-of-the-art mass spectrometry services and expertise while expanding MS applications across the Life Sciences spanning biology, chemistry and pharmacy.
We aim to build on our status as a Waters World Centre of Innovation in HDXMS and a SCIEX Regional Centre of Distinction to other areas of mass spectrometry applications through partnerships with individual researchers and industrial collaborations.
- In-gel Protein Identification
Identification of protein from gel bands/spots by MS
- Shotgun Protein Identification
Complex protein mixture (e.g. co-IP/pull-down sample)
- Molecular Weight Determination
Determining molecular weight of intact protein in solution by MS
- Post-Translational Modifications
Methods to study post-translational modifications such as sumoylation etc.
Protein identification and phosphorylation analysis
- Protein Structure, Dynamics and Interactions
Amide hydrogen/deuterium exchange mass spectrometry (HDXMS)
- Quantitative Proteomics
Unbiased comparative quantification of proteomes using label-based (iTRAQ, iCAT, SILAC) or label-free (SWATH/DIA) technologies
- Targeted Mass Spectrometry
Selective relative/absolute quantification of target molecules using multiple reaction monitoring (MRM)
