RECOMBINANT PROTEIN BIOSENSORS AND A METHOD FOR DETECTING THE PRESENCE OF AN ANALYTE MOLECULE

摘要

The present invention refers to a fusion protein biosensor, comprising a peptide or protein domain that binds an analyte of interest (A), an entity that can produce a detectable signal (B), and an entity that binds to B and modulate the signal produced by B when A is not bound to the analyte. A method and a kit for detecting a presence or amount of an analyte molecule using the fusion protein is also disclosed.
