Topic Study of biomolecular interactions by capillary electromigration methods
Faculty FCHT / FPBT VŠCHT, PřF UK
Abstract

The thesis will be oriented to the development of new high-performance electromigration methods, affinity capillary electrophoresis and affinity open-tubular capillary electrochromatography, and on their application to the investigation of the non-covalent interactions of biologically active peptides, proteins, nucleosides, nucleotides and other biomolecules with low- and high-molecular-mass ligands or receptors. New procedures will be developed for quantitative characterization of both weak and strong interactions of biomolecules in a free solution and on the interface of the liquid and solid phases. Interactions of biomolecules, e.g. peptide hormones or drugs with receptors, enzymes with substrates and inhibitors, and ionophores with small ions in a free solution will be investigated by different modes of affinity capillary electrophoresis. Interactions of biomolecules on the interface of solid and liquid phases will be studied by affinity open tubular capillary electrochromatography with ligands or receptors immobilized on the inner surface of the fused silica capillary. Strength of the interactions of biomolecules will be quantified by the stability constants of their complexes.
