Proteomics and (bio-)pharmaceutical applications
The novel stationary phases and separation methods developed in the department are applied to successfully tackle the truly complex separation problems arising from proteomics and (bio-) pharmaceuticals research.
Novel performance limits have been established for the 1D-LC separation of complex peptide samples using monolithic column technology and coupled columns packed with core-shell particles. In addition, the separation of intact proteins, including protein isoforms arising from various amino-acid modifications, has been demonstrated employing a poly(styrene-co-divinylbenzene) monolithic capillary column in high-performance liquid chromatography coupled on-line to a time-of-flight mass spectrometer (TOF-MS).
