What is Biacore technology?
Biacore products measure biomolecular interactions, including protein-protein interactions, small molecule/fragment-protein interactions, etc. Its technology is often used to measure not only binding affinities, but kinetic rate constants and thermodynamics as well.
What is Rmax in Biacore?
Rmax = theoretical max response for analyte binding. Sm = stoichiometry of Analyte/Ligand. RL = RU of immobilized ligand (target density). o For protein analytes, set RL such that Rmax is below 150. For pilot experiments you may aim higher, in case of low surface activity.
What is Biacore T200?
Biacore T200 is a versatile and precise surface plasmon resonance (SPR) system that provides you with a wide range of high-quality molecular interaction data. Sensitivity that allows you to generate high-quality molecular interaction data — from compounds to viruses.
What is Biacore T100?
Biacore T100 can be used to monitor almost any molecular interactions as long as one of the interacting partner can be immobilized on a sensor surface. It characterizes molecules in terms of the specificity of interaction, on and off -rates (kinetics), binding strength (affinity) and thermodynamics.
What is Biacore analysis?
Biacore SPR biosensors, which measure real-time analysis of biospecific interactions without the use of labeled molecules, can be used for a wide variety of protein interaction assays. In this unit, examples and recommendations for studying protein interactions with a variety of molecules are provided.
How does Biacore SPR work?
Principles of surface plasmon resonance (SPR) used in Biacore …
How do you calculate Rmax?
Rmax is determined by the relative molecular weight ratio between ligand and analyte and the amount of immobilized ligand. If the interaction is not 1:1 the Rmax is also determined by the binding stoichiometry.
How do you find theoretical Rmax?
1. Desired Theoretical Rmax = (MWanalyte/MWligand) x [Immobilized Ligand (RU) x % of theoretical Rmax] x Stoichiometry 2. Desired Theo. Rmax = 150 = (30/150) x Immobilized Ligand (RU) x 0.82 x 2 3.

What is surface plasmon resonance used for?
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 does surface plasmon resonance work?
2.1.
Surface plasmon resonance occurs when a photon of incident light hits a metal surface (typically a gold surface). At a certain angle of incidence, a portion of the light energy couples through the metal coating with the electrons in the metal surface layer, which then move due to excitation.
What is the purpose of SPR?
About the SPR
The Strategic Petroleum Reserve (SPR), the world’s largest supply of emergency crude oil was established primarily to reduce the impact of disruptions in supplies of petroleum products and to carry out obligations of the United States under the international energy program.
What is SPR assay used for?
What is the difference between Rmax and R?
r indicates the growth rate at any instant, so is independent of generation time and can be applied to any pop. rmax gives maximal pop growt rate (in absence of density-dependent limitations) wile r is actual rate, usualy affected by density dependent factors.
How is carrying capacity calculated?

How much does a BiaCore T200 cost?
How does SPR work?
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 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.
How is surface plasmon resonance measured?
A spectral method based on surface plasmon resonance (SPR) in air is used to measure the dielectric function of a thin metal film. The method utilizes the spectral dependence of the ratio of the reflectances of p- and s-polarized waves measured in the Kretschmann configuration at different angles of incidence.
What are the applications of surface plasmon resonance?
SPR is a powerful label-free method widely used to study binding between two macromolecules [12–15]. Typically, one of the two interacting partners is immobilized on a sensor chip surface, and the other is flowed through a microfluidic system in contact with the chip surface.
What is the principle of SPR?
General Principle of SPR. Surface plasmon resonance occurs when a photon of incident light hits a metal surface (typically a gold surface). At a certain angle of incidence, a portion of the light energy couples through the metal coating with the electrons in the metal surface layer, which then move due to excitation.
How is SPR measured?
To measure the SPR angle, the change in the intensity of the reflected light with the angle of incidence is monitored. The angle of incidence is changed by rotating the turntable connected to an angular displacement transducer (Figure 3). The intensity of the reflected light is measured by a silicon solar cell.
Where are Yamaha RMAX built?
