Determination of kinetic rate and equilibrium binding constants for macromolecular interactions: a critique of the surface plasmon resonance literature.

Over the past year, the BIAcore system (which is based on the surface plasmon resonance phenomenon) has become increasingly popular for the study of macromolecular interactions. This biomolecular interaction analysis system allows the detection of macromolecular interactions in real time and in a label-free mode. The real-time detection properties of this technique suggest its potential in the generation of data relating to the kinetics of interaction of biomolecules.
