A method for the detection of ligands by means of biosensors

摘要

A method for the detection of ligands 10 by means of biosensors 6, which on the forster resonance energy transfer principle are based, wherein a biosensor 6 is a protein which comprises three sections, whereby the first section has the function of a donor 7, wherein the second section has the function of an acceptor 8 and wherein the third portion of the first section and the second portion. 5, wherein the third section a region for the interaction with the ligand to be detected 10, and wherein the interaction reaction a change in the geometric structure of the third section, wherein the third section a to the binding of cyclic nucleotides suitable protein 1 is a prokaryotic.
