| Outline of Final Research Achievements |
Highly selective and effective purification methods for peptides and proteins have been developed. One is for polyamino-containing peptides. The amino moieties of peptides are perfluoroalkylated with amine-reactive fluorous reagent, then the derivatives are highly selectively extracted to a fluorous solvent, followed by LC/MS/MS analysis. The other is for phosphorylated peptides. The Fe(III) immobilized fluorous reagent is designed and synthesized. The reagent reacts with phosphorylated peptides to form their fluorous chelates, those are extracted selectively into a fluorous solvent. The former is applied to the determination of brain peptides in rat brain samples, and the latter to the assay for protein kinase activity.
