The Proteomics Research Translational Technology Platform (TTP) offers collaborative proteomics research support for projects at the Cancer Institute and within the CRUK City of London Centre.
The Proteomics Research TTP provides infrastructure for the identification and quantification of proteins and their post-translational modifications (PTMs). This includes expertise in PTM enrichment strategies, peptide separations, state-of-the-art mass spectrometry (MS) for discovery-driven experiments as well as targeted workflows for sensitive and consistent quantitative monitoring of pre-selected sets of proteins. The pathform continuously develops and adapts new sample preparation techniques, MS approaches and software tools to provide optimal analytical solutions for individual research projects. The PRTTP should be involved in all stages of a project to facilitate the use of an appropriate experimental design leading to accurate data interpretation.
Proteomic research at the Cancer Institute is led by Silvia Surinova - Team Lead in Proteomics, supported by Amandeep Bhamra - Mass Spectrometry and Proteomics Specialist and overseen by a scientific committee
How do I start a proteomic collaboration?
In order to establish a proteomic collaboration, you will need to submit a project proposal. Please request a proposal form by email (s.surinova@ucl.ac.uk). Proposal requests are reviewed by the scientific committee and successful proposals will be further discussed between proteomic experts and researchers. Typically, details of experimental conditions, analytical strategies, tailored data analysis and expected results interpretation will be determined prior to collaboration starting.
