Chromatographic and fluorometric study of interactions between thiophilic and hydrophobic ligands and tryptophan peptide homologues.
The interactions of tryptophan and its peptide homologues with thiophilic ligands were studied in terms of their chromatographic retention and steady-state fluorescence under various conditions, and compared with non-polar structures typically regarded as pure hydrophobic ligands. The experimental results show that both non-polar and polar interactions are involved in what has been termed "thiophilic adsorption chromatography".
