Biacore

Biacore is a life science products company, based in Sweden. In June 2006 GE Healthcare acquired Biacore for $390 million.

Biacore specializes in measuring protein-protein interaction and binding affinity. The technology is based on surface plasmon resonance (SPR), an optical phenomenon that enables detection of unlabeled interactants in real time. The SPR-based biosensors can be used in determination of active concentration as well as characterization of molecular interactions in terms of both affinity and chemical kinetics.
