Therefore, a high-resolution glucose detection method is required for detecting glucose concentration in diluted ISF. In this paper, an optical surface plasmon resonance (SPR) sensor modified by the glucose/galactose-binding (GGB) protein which has good affinity to glucose molecules was presented for specific and sensitive glucose detection.
Applied assay technologies comprise surface plasmon resonance (SPR), e.g. from Biacore TM /Cytiva (formerly GE Healthcare immobilization of the ligand is of considerable importance for the reliable determination of the binding kinetics of In addition, immobilization of the antibody to the sensor surface can affect its affinity to the
Together they form a unique fingerprint. Surface Plasmon Resonance Medicine & Life Sciences Kinetics Medicine & Life Sciences Commercial surface plasmon resonance (SPR) instruments such as Biacore have been widely used to measure receptor-ligand binding kinetics using ligands that are covalently attached on functionalized gold sensing surfaces. 9,10 However, adapting conventional SPR instruments for sensing with fluid lipid membranes presents a series of challenges. The aim of this study was to compare the affinity values obtained for a monoclonal antibody/antigen complex using two different techniques, surface plasmon resonance (SPR) and an enzyme linked immunosorbent assay (ELISA) approach recently described by Bobrovnik S.A. and by Stevens F.J. 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.
In Surface Plasmon Resonance (SPR) assays, just like in any biophysical or biochemical experiment, it’s important to make sure the samples used are suitable for the job. Low quality proteins can lead to tedious assay optimization, hard-to-understand results, and the need for professional support to work out what’s wrong.

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 (SPR) is now widely embraced as a technology for monitoring a diverse range of protein-protein interactions and is considered almost de rigueur for characterizing antibody-antigen interactions. The technique obviates the need to label either of the interacting species and t …. A developing technique in this respect is surface plasmon resonance (SPR) spectroscopy, which is label-free and enables measurement of real-time quantification of ligand-binding affinities and kinetics using relatively small amounts of membrane protein in a native or native-like environment and has potential to be medium-throughput. Surface plasmon resonance is an excellent method for monitoring changes in the refractive index in the near vicinity of the metal surface. When the refractive index changes, the angle at which the intensity minimum is observed will shift as indicated in Figure 1.2 , where line A depicts the original plot of reflected light intensity versus incident angle, and B is the plot after the change in refractive index. determine the on and off rates and affinity constant for the interaction between prostate specific antigen (PSA) and its antibody (anti-PSA). Results are compared against industry standard surface plasmon resonance instruments.
