The widely adopted Biacore T offers reliable ligand-binding assays—as described in regulatory guidelines—to characterize and assess comparability, even for the most complex biologics.
At a particular wavelength and incident angle, a surface plasmon wave of excited electrons the plasmon resonance bicore produced at the gold layer and is detected as a reduced intensity of the reflected light beam. A baseline SPR angle is first determined by washing buffer over the surface with a fixed amount of ligand attached.
F200, having very high levels of ligand immobilised on the surface has two important implications for the technique.
Under these conditions, an electromagnetic component of the beam, the evanescent wave, propagates into the biaxore layer and can interact with mobile electrons in the gold film at the surface of the glass. The optical device has no moving parts and the fixed geometry enhances stability and allows binding to be monitored in real time. In Biacore instruments, monochromatic light in the shape of a wedge a broad distribution of incident angles is used.

These analyses can be performed using a multicycle approach many samples against one ligand or when different ligands are immobilizedor alternatively, using singlecycle kinetics fast runs without regeneration.

This background response must be subtracted from the sensorgram to obtain the actual binding response.

Please follow the link for information regarding the Booking and rules for use of the BIAcore T instrument: No reviews have been left for this product. The binding of analyte to immobilized h200 causes an increase in the refractive index at the surface, thereby changing the SPR angle because it is directly proportional to the amount of bound analyte.
The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC The precision and automation of the system generates highly reproducible data. A related problem is that, following dissociation of the analyte, it can rebind to the unoccupied ligand before diffusing out of the matrix and being washed from the flow cell.
Be the first to leave a review! This refractive index change is measured in real time tt200 in a kinetic analysis experiment is taken every 0. Software-supported direct binding and inhibition assays enable measurement of active concentration. How to get started. Download technical information on the T system. If this condition arises, mass transport becomes the rate-limiting step, and as a consequence, the measured apparent on-rate will be slower than the true biaacore.
There’s no available product features to display for this product variant. The underlying physics of the principles of SPR are complicated. Its binding partner termed by BIAcore as the analyte is then injected in aqueous solution ideally with the same components and composition as the running buffer through the flow cell, under giacore flow.
We will be in touch with you shortly. The software provides dedicated tools for immunogenicity testing for confident detection and characterization of anti-drug antibodies ADA during preclinical and clinical development.

However, a working knowledge of the technique doesn’t require a detailed understanding of the theory. Each angle of the reflected beam strikes the instrument’s detector at a different point and, thus, the detector continuously records the position of reduced light intensity and calculates the SPR angle from that figure.
The SPR optical unit consists of a source for a light beam that passes through a prism and strikes the surface of a flow cell at an angle, such that the beam is totally reflected. Such high ligand density may result in the rate at which the surface binds the analyte exceeding the rate at which the analyte can be delivered to the surface this latter consideration is referred to as mass transport. Only bound protein generates a positive SPR signal and that signal, recorded over time, produces a sensorgram.
If you can’t find what you need, contact us to solve your problems. One RU represents the binding of 1 pg of protein per square mm. Consequently, the measured apparent off-rate is slower than the actual off-rate.
Fast, simple kinetic analysis Biacore T software offers a range of tools for confident and reliable kinetic analyses. Calibration-free concentration analysis CFCA is of great value when no satisfactory calibration standard is available.
To this flow of buffer, some analyte is then added.
Biacore T is a versatile system for t20 characterization of molecular interactions, from ions to viruses. If the added molecule does not bind to a target or receptor, the SPR angle change in the sample and reference flow cells will be the same, and, after subtraction, will give a zero net RU response that indicates no binding occurred.

As the analyte binds to the ligand the accumulation of protein on the sensor surface causes an increase in refractive index. To allow the detection of an interaction one molecule termed by BIAcore as the ligand is immobilized onto the sensor surface.
