Surface Plasmon Resonance System
Biacore T200 SPR, Cytiva
Surface Plasmon Resonance (SPR) is a sensitive, label-free technique that monitors molecular interactions in real-time. In SPR, one interacting partner is immobilized onto a sensor surface and the other is flowed over the surface. Binding between the interaction partners leads to changes in mass near the sensor surface, which is detected by the instrument as subtle changes in refractive index.
SPR can be used to rapidly provide quantitative information about interactions between proteins, nucleic acids, lipids, drugs, inhibitors and other organic compounds, such as binding affinity, kinetics, specificity, and concentration. Thermodynamic parameters can also be quantified by SPR via temperature variation. SPR can analyze interactions in various solutions, from clear buffers to cell supernatants and blood plasma.
For more information, see this seminar on SPR that the BIC hosted.
