Marc Driessen, associated with the protein research group and the local core facility at the University Hospital Dusseldorf, explains the significance of glycoproteins, particularly in diseases like cancer, due to their involvement in various biological pathways. The discussion includes the complexity of glycans, particularly distinguishing between N-glycans and O-glycans, and emphasizes the importance of enriched glycopeptides for effective analysis. Traditional methods of glycoprotein analysis are contrasted with more modern approaches, such as mass spectrometry (MS) and proteomics, highlighting the challenges and benefits of each technique.

Furthermore, the presentation delves into the optimization of workflows for glycoprotein enrichment and analysis. The speaker presents a streamlined workflow developed in collaboration with core facilities, emphasizing the need for efficient lab procedures and reliable analysis methods. Evaluations using standard cell lines, various digestion methods, and MS techniques reveal insights into the reliability and effectiveness of different fragmentation energies and software tools. Additionally, the speaker discusses advanced methods like metabolic labeling and orthogonal techniques for enhancing glycoprotein coverage, addressing challenges such as signal dilution and glycan heterogeneity.
