Phosphorylation and glycosylation are two common posttranslational modifications (PTMs) of proteins that perform critical roles in the regulation of many cellular processes including cell cycle, signal transduction pathways, recognition, gene expression and cellular immunity.

Mass spectrometry is a powerful tool for the detection and identification of PTMs. Comprehensive characterization of proteins include localization of the modification site, characterization of structures and quantification of the various modified forms to fully understand the effect on protein function. Electron Transfer Dissociation (ETD) is a fragmentation technique that has been used enthusiastically for peptide identification, localization of labile post-translational modifications (PTMs) and sequence polymorphisms.

This webinar demonstrates the advantages of using a novel Orbitrap mass spectrometer for qualitative and quantitative PTM analysis. The novel arrangement of the three mass analyzers plus advances in software not only increases the rate of high quality ETD spectra, but also the ease of routinely obtaining high quality ETD data.

Enhanced peptide ID will be discussed as well as PTM identification and localization for both phosphorylation and glycosylation.

Key Learning Objectives:

  • Understanding unique capabilities of Orbitrap Fusion MS and ETD for PTM analysis
  • Complete quantitative and qualitative PTM workflows

Who Should Attend?

  • Protein Chemists
  • Biologists
  • Proteomics Researchers

Shannon Eliuk: Biography

Shannon Eliuk did her graduate studies at University of Alabama at Birmingham focusing on applying mass spectrometry to study protein oxidation in Alzheimer's disease. She then joined the lab of Prof. Al Burlingame at University of California San Francisco as a post-doctoral scholar where she performed a variety of proteomics techniques including top down, middle down and bottom up proteomics combined with label free and SILAC-based quantitation to study histone modifications in embryonic stem cells. After joining Thermo Fisher Scientific three and a half years ago, she worked on many application and instrument development projects, most recently the exciting new development of Orbitrap Fusion with ETD.
