Aebersold lab, student (master) project in phosphopeptide enrichment.
We are looking for students who would like to join project for development of the new phosphopeptide enrichent for the analysis of small sample amounts. These projects are the perfect opportunity to get hands-on experience with proteomics methods and mass spectrometry instrumentation. Prior experience with mass spectrometry is not essential, although candidates with basic knowledge of proteomics methods are preferred.
Protein phosphorylation is one the most important post-translational modifications with relevance for many biological processes, e.g. signal transduction. Phosphoproteomics aims to comprehensively characterize this modification by mass spectrometry. To be able to detect phosphorylation events, proteins are enzymatically digested and phosphopeptides enriched by various affinity materials. Our group has a strong track record in developing phosphoproteomics methods and applying them to highly relevant research questions in systems biology and biomedicine.
Currently, we are evaluating different affinity materials based on metal oxides for the analysis of small sample amounts and are looking for students to support us in this endeavor.
You will learn how to perform phosphopeptide enrichment, process your samples for MS analysis, analyze the samples by LC-MS and perform the data analysis. These projects are the perfect opportunity to get hands-on experience with proteomics methods and mass spectrometry instrumentation. You will contribute to important projects that will have immediate impact on cutting-edge research in the group. Prior experience with mass spectrometry is not essential, although candidates with basic knowledge of proteomics methods are preferred.
