Materials & Equipment OpenSPR Instrument (SPR-01) TracerDrawer Kinetic Analysis Software (TDS) Fingerprint Dive into the research topics of 'Use of surface plasmon resonance (SPR) to determine binding affinities and kinetic parameters between components important in fusion machinery'. 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.

Surface plasmon resonance binding affinity

In this paper we report the development of a DNA biosensor based on Surface Plasmon Resonance (SPR) for studying DNA-binding molecules. The study and the identification of compounds which can interact with DNA and interfere with gene expression is important in many areas such as pharmacological, medical or environmental analysis.

SPR can be performed by either cross-linking a given ligand to a sensor chip covalently or utilizing high-affinity non-covalent interactions to secure a ligand in a particular conformation to a chip, both of which have their potential advantages. Surface Plasmon Resonance imaging allows monitoring many label-free molecular interactions in parallel to give information on kinetic rates and binding affin In the current study, we examined the affinity maturation of a binding protein using in silico analysis in combination with surface plasmon resonance (SPR).

Surface plasmon resonance is an analytical technique for studying molecular interactions. Surface plasmon resonance or SPR is an optical effect that can be utilized to measure the binding of molecules in real-time without the use of labels. SPR instruments are primarily used to measure the binding kinetics and affinity of molecular interactions.

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.

SPR can be performed by either cross-linking a given ligand to a sensor chip covalently or utilizing high-affinity non-covalent interactions to secure a ligand in a …. Use of Surface Plasmon Resonance (SPR) to Surface plasmon resonance (SPR) is one of the most commonly used techniques to study protein-protein interactions. The main advantage of SPR is it gives on the ability to measure the binding affinities and association/dissociation kinetics of complexes in real time, in a label-free environment, and using relatively small quantities of materials.

In this work, we developed a membrane biosensing platform based on surface plasmon resonance in gold nanohole arrays with a series of surface modification techniques to form myelin-mimicking lipid bilayer membranes to measure both the association and dissociation rate constants for O1 and O4 antibodies binding to their myelin lipid antigens.

Surface plasmon resonance (SPR) is a powerful technique for monitoring the affinity and selectivity of biomolecular interactions. SPR allows for analysis of association and dissociation rate constants and modeling of biomolecular interaction kinetics, as well as for equilibrium binding analysis and ligand specificity studies.
