Since the wave is on the boundary of the metal and the external medium (air or water for example), these oscillations are very sensitive to any change of this boundary, such as the adsorption of molecules to the metal surface.

Surface plasmon resonance binding affinity

The system is used to deliver high-quality kinetic, binding affinity, concentration, specificity, selectivity, and thermodynamic interaction data, all with high sensitivity. Based on Surface Plasmon Resonance (SPR) technology, the Biacore T200 system significantly enhances performance so that the upper and lower limits of kinetic ranges can be assessed.

SPR occurs when the total internal reflection of polarized light takes place at a metal film. SPR instruments are generally used to measure affinity and the binding kinetics of the molecular interactions. Surface Plasmon Resonance (SPR) SPR Assay Services for Drug Discovery Surface Plasmon Resonance (SPR) is a highly sensitive technique for accurate measurement of the interactions of two biomolecules with respect to binding kinetics and affinity as well as binding specificity. Kinetic analysis using surface plasmon resonance (SPR) is another option to obtain dynamic information about antibody-antigen interaction.

Since its commercialization in 1990’s, SPR has made vast advances in terms of both development of the technology and its applications. A surface plasmon resonance-based solution affinity assay is described for measuring the K d of binding of heparin/heparan sulfate-binding proteins with a variety of ligands. The assay involves the passage of a pre-equilibrated solution of protein and ligand over a sensor chip onto which heparin has been immobilised.

A novel strategy for characterizing NGF inhibitors was used to determine the binding affinity (K D) and saturation ability of each compound with immobilized NGF. Seventy-four percent of compounds screened demonstrated a positive binding event to NGF. A K D Surface sensitive biosensors, such as surface plasmon resonance (SPR) and surface acoustic wave sensors, require elaborate design of the sensing surfaces in order to accomplish favourable orientation, high purity, long-term stability, and high activity of their capturing ligands [1-4]. Applied assay technologies comprise surface plasmon resonance (SPR), e.g.
