What does Biacore measure?
SPR (Biacore) assays provide a method for determining the affinity and binding kinetics of a ligand for its receptor. The technique measures the real-time binding association and dissociation rates using Surface Plasmon Resonance (SPR).
What is an SPR test?
Introduction. Surface plasmon resonance (SPR) binding analysis methodology is used to study molecular interactions (1, 2). SPR is an optical technique for detecting the interaction of two different molecules in which one is mobile and one is fixed on a thin gold film (1).
How is SPR performed?
SPR occurs when polarized light strikes an electrically conducting surface at the interface between two media. This generates electron charge density waves called plasmons, reducing the intensity of reflected light at a specific angle known as the resonance angle, in proportion to the mass on a sensor surface.

What are the uses of SPR?
SPR instruments are primarily used to measure the binding kinetics and affinity of molecular interactions. SPR can be used, for example, to measure the binding between two proteins, a protein and an antibody, DNA and a protein, and many more.
What is an SPR instrument?
SPR is a sensitive spectroscopic tool for studying molecular interactions in a label-free state. The system detects binding in real-time by measuring mass changes of a ligand, which is bound to a chip, as analyte is flowed over the chip.
What is surface plasmon resonance?
Surface plasmon resonance (SPR) is a phenomenon where the electrons in the metal surface layer are excited by photons of incident light with a certain angle of incidence, and then propagate parallel to the metal surface (Fig. 10.17; Zeng et al., 2017).
What is Biacore technology?
The Biacore platform monitors molecular interactions in real time by using a non-invasive label-free technology. This technology reacts to changes in the concentration of molecules at the sensor surface as molecules bind to or detach from the surface.
Why is SPR used?
Why prism is used in SPR?
The main reason for using the prism here is to provide the evanescent field (via the total internal reflection, TIR) that excites plasmons in a metal film that is coated on a base of the prim.
What is Otto configuration?
When using light to excite SP waves, there are two configurations which are well known. In the Otto configuration, the light illuminates the wall of a glass block, typically a prism, and is totally internally reflected.
