Detecting Proteins’ “Rendezvous”
by using firefly’s light-emitting mechanism

Analyzing protein-protein interaction is essential to elucidate finely tuned life phenomena. Prof. Ueda and his co-workers have developed a novel technology, named “Firefly luminescent intermediate based Protein Interaction Assay (FlimPIA)”, to detect these interactions by combining two complementary luciferase mutants. Highly sensitive and specific, this technology demonstrated under-1-second detection of several known protein-protein interactions in a concentration-dependent manner.

FlimPIA may be applied to drug discovery and clinical diagnostics as a convenient, high speed and specific assay.
