Guide and selection support
Surface plasmon resonance (SPR) systems are used to analyze binding interactions between biomolecules, such as in the study of protein interactions or for molecular analysis. They provide real-time data without the need for additional labeling, allowing for fast and direct measurements. Key selection criteria include system sensitivity, flexibility in sample delivery, and compatibility with various molecule types. LabFinder supports you in finding suitable SPR systems through a clear overview and search terms that simplify your procurement process.
Use and Benefits
Surface plasmon resonance systems (SPR systems) are primarily used in biophysical research to analyze molecular interactions in real time and without labeling. Applications include the characterization of binding for ions, small molecules, proteins, and even viruses. The technology provides quantitative data on affinities, kinetics, and thermodynamic parameters, which are essential for studying molecular interactions.
Selection Criteria
When choosing an SPR system, sensitivity and flexibility are primary considerations. Important aspects include the type of sensor surface, options for sample delivery (such as microfluidic integration), and suitability for the types of molecules being studied. Throughput capacity and processing software for data analysis and interpretation are also important.
Variants and Measurement Principles
SPR systems operate based on optical measurement of changes in surface plasmon resonance caused by the binding of molecules on the sensor surface. Variants mainly differ in sensor chip technology, detector type, and sample delivery technique, such as stationary cells or microfluidic modules.
Calibration and Maintenance
The systems require regular calibration to ensure measurement accuracy, often using standard samples or reference substances. Maintenance work includes cleaning the sensor chip and fluidic systems as well as inspecting the optical components.
Limitations of Application
Surface plasmon resonance systems are limited to detecting molecular interactions at a surface and cannot perform volumetric measurements. Sensitivity depends on the sensor surface and can be affected by nonspecific binding or sample content. Additionally, operation requires technical expertise.

Frequently asked questions
How does a surface plasmon resonance system work?
The system measures changes in the resonance frequency of plasmons at a metal surface caused by binding events between molecules in real time, without the need for molecule labeling.
What types of molecules can be analyzed with SPR systems?
SPR systems can investigate a wide range of molecules, including ions, small molecules, proteins, nucleic acids, as well as viruses and viral components.
What are important criteria for choosing an SPR system?
Sensitivity, flexibility of sample delivery, compatibility with different molecules, throughput, and software support are key selection criteria.
What maintenance is required for SPR systems?
Regular calibration, cleaning of sensor chips and fluidic systems, and inspection of optical components are standard maintenance tasks to ensure measurement accuracy.
What limitations do surface plasmon resonance systems have in analysis?
SPR only measures binding at the sensor surface, is susceptible to nonspecific binding, and requires experienced operation. Volumetric analyses are not possible.
