Platform technologies for the analysis of glycosaminoglycans and mediator proteins

Prof. Martin von Bergen, Johannes Schmidt, Florent Jouy, Nagarajan Kumaran

Within the scope of subproject Z4, qualitative and quantitative protein analysis is carried out as a service for all Transregio 67 projects. For this purpose, the development of methods for the highly sensitive detection of low molecular weight proteins as well as highly modified proteins, including cytokines and growth factors, is being developed.

  • The identification and quantification of proteins extracted by microdialysis from injured tissue during the wound healing process by means of nano-HPLC / nano-ESI mass spectrometry
  • Protein expression analysis from cell models
  • Enrichment and determination of glycosylation
  • Protein separation by 1D / 2D-SDS-PAGE or HPLC (size exclusion chromatography, C4 reverse phase chromatography)
  • Implementation of trainings / introduction of TRR67 employees.
