How Much Does an SPR System Cost?

Surface Plasmon Resonance (SPR) enables real-time analysis of molecular interactions without the need for labeling, making SPR systems indispensable across various scientific disciplines, such as drug development, biomolecular research, and material science, offering precise insights into binding kinetics, affinity, and concentration.

If you’re looking to acquire an SPR system for your lab, you’ll start to notice that the cost can vary widely. This range is influenced by factors such as sensitivity, throughput, and additional features. 

In this article, we’ll review some popular SPR systems and their price ranges, as well as the key factors that affect cost differences. Hopefully this helps when it's time to make a procurement decision. Balancing your research needs and budget will be key.

What Is an SPR System?

An SPR system detects changes in the refractive index near a sensor surface, typically a thin gold-coated metal film. When polarized light hits this film at a specific angle, it excites surface plasmons—electron oscillations at the metal-dielectric interface. Any binding events on the sensor surface cause a shift in the angle at which SPR occurs, which is then detected and analyzed to provide detailed interaction data. 

Components of SPR Systems

An SPR system relies on several key components working together to analyze molecular interactions in real time:

• Sensor Chip: This is where the action happens. Usually coated with a thin metal film like gold, the sensor chip can be customized with ligands or capture molecules specific to your target analyte.
• Light Source: Typically, a laser or LED provides the polarized light directed onto the sensor chip.
• Optical System: Comprising a prism, optical fibers, and detectors, this system directs light onto the sensor chip and captures reflected light to measure angle or intensity changes.
• Flow Cell: This chamber introduces samples and analytes over the sensor surface, enabling continuous or discrete analysis.
• Detector: Measures changes in light reflection or intensity as it interacts with the sensor surface, providing data to calculate shifts in the SPR signal.
• Control and Analysis Software: This software runs the show, managing system operation, data acquisition, processing, and detailed analysis of interaction data.

These components combine to provide real-time, high-precision monitoring of molecular interactions.

Main Features of the SPR System

SPR systems come with features that make them indispensable for real-time molecular interaction analysis. The most important features include label-free detection, real-time interaction analysis, and high sensitivity:

• Label-Free Detection: One of the biggest perks of SPR is that it doesn’t require fluorescent or radioactive labels, allowing you to study molecular interactions in their natural state without interference.
• Real-Time Interaction Analysis: SPR systems shine by providing real-time analysis, letting you observe and measure binding events as they happen, which is crucial for studying dynamic processes and gaining insights into binding kinetics and affinity.
• High Sensitivity: These systems are incredibly sensitive, capable of detecting even the smallest changes in the refractive index near the sensor surface, making them ideal for analyzing a wide range of interactions, from strong, high-affinity bindings to weaker, transient associations.

These features make SPR systems essential for detailed molecular research.
