Method for studying the interaction of biomolecules using surface plasmon resonance

摘要

The invention concerns a process, a biosensor unit which can be regenerated and suitable kits for investigating the interaction between biomolecules by means of surface plasmon resonance (SPR). One of the reagents, a (poly)peptide, is coupled to the surface of the biosensor unit by means of a metal chelate. Nitrilotriacetic acid derivatives to which proteins with an affinity peptide containg histadine groups can be bonded are preferably used as chelate formers.
