Spend less money on equipment and maintenance — and more on your research — when you choose a 2SPR. In fact, the typical research lab can save $17,000 per year, per system, compared to the equivalent performing systems. That’s $85,000 over the next five years — valuable funds that you can use for your staff and other critical research needs.
Purchasing a 2SPR System typically costs $25,000 less than the leading competitor.
Every SPR machine requires chips to couple proteins to. A typical lab can use 75–200 sensor chips each year, which is why you should always ask about the cost of chips when you’re considering an SPR system. XanTec bioanalytics offers the biggest choice of high-quality sensor chips plus reagents which cost significantly less than our competitors, so you can run more experiments without worrying about out-of-control costs.
Other SPR companies make you purchase a service contract, which can easily cost up to $150,000 over the course of five years. With our 2SPR System, all of the typical parts that need maintenance are easy for you to access (and service) yourself. Of course, we do offer service contracts, if you would rather let us handle the regular maintenance.
The Reichert 2SPR System offers significant advantages for researchers and scientists. Whether you’re working with simple solutions or more challenging assays, you can count on Reichert to offer:
Other SPR systems only allow for limited access to critical parts. But with the 2SPR, everything you need to access is right out in the open, which makes your life — and your research — much easier.
The Reichert 2SPR System is designed to be as flexible as possible, from changeable tubes to an easily accessible flow cell. Wherever your research takes you in the future, you can be rest assured that we will let you stay on track, without costly upgrades and changes.
With our SPR systems, you can change the tubing whenever you want in just minutes — without having to wait around for a service call. That’s because all Reichert SPR systems are designed to use low-cost, off-the-shelf HPLC fittings and tubing that are easily accessible to you and your staff. With these systems, you can:
While some competitors require you to replace a flowcell cartridge once or twice a year, our flow cells are easy to clean (and, if necessary, change) yourself and are not a consumable. We offer standard flow cells, as well as specialized flow cells that can be used simultaneously with other valuable analytical techniques, opening up new opportunities for investigation in SPR experiments.
Our sensor chips perform equivalently or better to the leading competitor’s chips, at a significantly lower cost. Additionally to the standard chips, XanTec offers several unique functionalities, found nowhere else on the market. These include:
Reichert’s open, component-based design lets you connect our 2SPR System to other modules, and gain valuable new information in a single experiment.
Our specialized flow cells let you:
XanTec and Reichert are names you can trust. Both have been developing cutting-edge SPR technology since 1997, selling to some of the top names in academics and private industry. While the instrument manufacturer Reichert has been in business for more than 140 years and is backed by the billion-dollar company, AMETEK, Inc., XanTec is offering the biggest sensor chip portfolio available on the market today.
At XanTec, we’re here for you — just as we have been for more than 25 years — with the expert service and support you expect from an industry leader.
Surface plasmon resonance (SPR) is a technique that lets you investigate biomolecular interactions (including, but not limited to, protein-protein binding and protein-small molecule binding) in real-time. With SPR, you can determine if there is an interaction with your protein or other target molecule — and, if so — answer questions about the interaction including:
If you have questions about whether or not SPR is right for your lab, please contact us.
SPR is typically used in academic and industry settings to advance research in a range of areas, including:
Whether you’re studying Alzheimer’s disease, developing new vaccines or focused on other areas of protein research, SPR can help you quickly determine whether proteins interact, and which ones are worth studying more.
With SPR, you work with native proteins, which means you don’t have to attach another molecule to one of your proteins. Instead, you’ll use our SPR device to immobilize one of your proteins on a small “chip,” and then flow your other protein or molecule over the chip to see the response and study the interaction.
SPR allows you to study a variety of interactions, including those involving:
With alternative tubing, you can also perform SPR on crude samples, including:
With SPR, you get a large volume of highly accurate information about protein interactions, including the strength of the interactions (affinities) and the binding kinetics — how fast the molecules are binding (associating) and dissociating. Other techniques don’t provide as much data and aren’t as accurate.

Reichert's powerful software platform for all 2-channel instruments, provides integrated data acquisition, automated sample handling, and data analysis:
Protecting the security and integrity of electronic records (ER) is essential for compliance. This includes ensuring the reliability and trustworthiness of ER used to support critical decisions. Features in Reichert’s SPR software include:
The software has been developed in accordance with an accepted development model to ensure adequate validation.
Developing an experimental method with drag and drop functionality is easy. To begin, a standard method can be dragged and dropped from the “Available Methods” section (center) to the run table window. The method can be quickly modified as necessary by the researcher. User defined methods can be saved for reuse in future experiments. In the example sequence, step 1 is a pump refill and step 2 is a 1-minute wait for baseline stabilization. The third step is a 2 minute 100µL sample injection from vial 1A followed by a 5 minute dissociation period. The final steps are a 50µL injection of a regeneration solution followed by a 1 minute dissociation. The checked “Rinse” box in an injection method washes the sample loop and needle with buffer prior to the next sample injection. Multiple injections are easily programmed by simply dragging and dropping a “Loop” command at the beginning and end of the methods that are to be run several times. The number of loops is set in a user-definable box in the loop end command. The vial position will automatically increment. This functionality easily facilitates scale-up of experiments in minutes, to take advantage of Reichert's high capacity autosampler - including injections from 96 and 384 well plates or 48 or 12 vial sample trays.
Data from the individual channels and difference can be viewed together or separately in real-time. Both the response (Y axis) and time (X axis) axis may be auto-scaled or set to user-defined limits. Individual cycles can be selected to quickly zoom in on an area of interest. The data window can also be expanded over a defined region to allow close examination of the SPR response curves. In addition, this window continuously displays the status of each system component, read time interval, flow rate, temperature, file name and injection/dissociation markers.
SPR sensorgrams are automatically extracted and aligned to the same zero start time and zero response. The aligned sensorgrams are then sent to the analysis package. In addition to Reichert's integrated package, data can be exported for use in other widely available packages, such as Scrubber.
Aligned sensorgrams are automatically transferred to the integrated data analysis package in one click. Once in the analysis module, users can fine-tune the alignment, perform background and blank subtractions, and adjust concentrations, if needed. Creating kinetic fits is a straight forward task, and results are clearly displayed. There are a number of kinetics models to choose from to ensure appropriate characterization of the experimental data. Data can be fit to a 1:1 binding model (with or without mass transport or depletion), or three different 2-site models (2:1 with or without conformational change, or 1:2). You can also fit Dissociation data only. Figure 1 shows results for data fit to a 1:1 binding model.
Additionally, when equilibrium responses are obtained, affinity analyses can be completed to create figures that are publication- ready (see Figure 2).
Summaries of ka(association rate constant) an kd(dissociation rate constant) can be presented as on/off plots by clicking the On/off rate map button in the summary tool. Each curve is presented as a coordinate in the ka/kd-space, which enables a fast overview of many compounds.
Reichert's Surface Plasmon Resonance software provides flexibility for users, enabling full control of experimental methods easily transition from collection to analysis to answers.
