Surface plasmon resonance binding affinity

SPR detects the resonant oscillation of conduction electrons in the immediate vicinity of the surface layer of a sensor chip in a real-time monitoring and label-free manner. In this paper we used an in house developed fiber-optic surface plasmon resonance (FO-SPR) biosensor to study the affinity and binding kinetics of phages, displaying peptide libraries. At this angle of incidence, the light will excite surface plasmons, inducing surface plasmon resonance, causing a dip in the intensity of the reflected light. Photons of p-polarized light can interact with the free electrons of the metal layer; inducing a wave-like oscillation of the free electrons, thereby reducing the reflected light intensity. One of such techniques is surface plasmon resonance (SPR) spectroscopy, a label-free technique which enables measurement of real-time ligand-binding affinities and kinetics using relatively small amounts of membrane protein in a native or native-like environment (Olaru et al., 2015). 1996-05-21 · The measured binding affinity of cholera toxin for the ganglioside sequence ranges from 4.61 × 10-12 M for GM1 to 1.88 × 10-10 M for asialo GM1. The picomolar values obtained by surface plasmon resonance are similar to K d values determined with whole-cell binding assays. 2017-05-22 · Surface Plasmon Resonance (SPR) is a widely used label-free detection technique for studying binding behavior of biomolecules.

2020-04-01 · Surface Plasmon Resonance is used to observe the change in refractive index at any surface. 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.
