Surface Plasmon Resonance (SPR) is a highly effective analytical technique for the label-free detection of a diverse array of analytes, as well as for real-time monitoring of biomolecular events. This includes the assessment of binding kinetics, affinity, and specificity of interactions between biomolecules, such as nucleic acids. CD Formulation provides an SPR technology platform that facilitates high-throughput screening of fragment libraries, determination of kinetics and affinity, analysis of binding specificity, and characterization of antibodies.
Surface Plasmon Resonance (SPR) technology is based on surface plasma waves generated when light interacts with a metal surface. When the frequency of the incident light resonates with the free electrons on the metal surface, a surface plasma wave is formed. The propagation of this wave alters the intensity of the incident light, resulting in a change in the intensity of the reflected light. When biomolecules bind to the metal surface, they modify the local refractive index, which in turn affects the propagation of the surface plasma wave, leading to a change in the intensity of the reflected light.
