Synthese von immobilisierten Peptidfragmenten an Polystyrol-Polyoxyethylen zur Affinitätschromatographie /Synthesis of Immobilized Peptide Fragments on Polystyrene-Polyoxyethylene for Affinity Chromatography
Abstract Polystyrene-polyoxyethylene craft copolymers have been used for step-wise peptide synthesis. After completion of synthesis the protecting groups are cleaved under acidic conditions, where the polymer-peptide bond is stable. These gels in comparison to polystyrene peptide gels, show better properties for applications in affinity chromatography as well as synthesis on solid supports, because the advantageous properties of polystyrene beads are combined with the excellent spacer behavior of polyoxyethylene chains (mobility, solvation by water and organic solvents). Peptide gels with polylysine sequences have been synthesized as highly selective stationary phases for the separation of the homologous oligo desoxyribonucleotides (dT)n with n = 1-3. The principal possibilities of these gels for affinity chromatography is demonstrated.
