Surface Plasmon Resonance (SPR) is a powerful technique to measure biomolecular interactions in real-time and label-free. The SPR biosensor relies on the detection of changes in refractive index which are related to mass changes at the sensor surface.
The SPR platform available as service is a dual channel SPR instrument which integrates computer controlled pumps, valves and injection fluidics. The biosensor platform allows real time analysis of binding events occurring at the sensor surface and has been applied in a wide range of applications like environmental monitoring, clinical diagnosis, nucleic acids detection, or in the study of antibody-antigen interactions or virus-protein interactions.
