Description
SPR NAVI™ 220A - THE AUTOMATED MP-SPR
SPR Navi™ 220A is the top of our line. Choose SPR Navi™ 220A, if you want to perform high-throughput MP-SPR with minimum dead-volumes and increased measurement confidence. As shown in the comparison, it is fully automated. Also here, to fully enjoy the MP-SPR, we recommend the additional set of lasers.
Key Features of SPR Navi™ 220A:
True Goniometric SPR
Unlike most SPR systems, SPR Navi™ 220A is a true goniometric SPR. This eanbles a wide angular scan range (= 40–78°) that produces a complete SPR curve with absolute angle information. The true goniometric SPR configuration confers great advantages as it widens the range of refractive indexes at which you can measure, allowing you to characterise surfaces in gas and/or liquid. It also allows you to check the quality of user-defined surfaces before sample injection, providing you with additional evidences. In other words, the wide angular scan range makes SPR Navi 200 an extremely sensitive and versatile characterization instrument.
Customizable flow cell
SPR Navi™ 220A comes with dual measurement channels for in-line referencing or duplicate measurements. In addition, the easily accessible flow-cell can be customized for user-specific experiments, thus broadening your experimental capabilities. For instance, BioNavis can provide electrochemical flow cells or flow cells equipped with optical fibers for surface illumination. The flow cell shape can also be customized to tailor the flow dynamics to your needs.
Flexible sensor-slide system
With the SPR Navi™ 220A instrument, you can use the innovative sensor-slide holder for easy “drop-in” placement of your sensor-slide into the instrument. It allows users to change surfaces within seconds, making SPR Navi™ 220A an extremely convenient instrument to work with. The sensor-slide holders can be labeled and used for long-term storage of your custom-modified surfaces. Sensor-slides can be modified outside the instrument, with a great number and combination of layers, prior to the actual analysis. This unique removable sensor system provides additional flexibility. It allows you to combine SPR data with other widely used techniques to provide supporting information, including surface topography, surface wettability, chemical composition, photochemical processes, swelling, adsorption...
Contamination free MP-SPR
The proprietary optical elastomer in the SPR Navi™ 220A finally does away with the need for messy and potentially contaminating index-matching oil. The result is a contamination-free environment for your measurements. The optional immobilizer, a horizontally oriented stand-alone flow cell, can be used for in-situ functionalization of SPR slides. This further minimizes the risk of cross-contamination and enables minimal sample depositions.

ANALYTICAL PERFORMANCE |
|
Measured property | SPR Navi™ instruments measure light intensity reflected from the sensor surface (absolute measurement), while traditional SPR instruments measure light shift (only a relative measurement). |

Noise level | 0.3 µRIU (short term) 1 µRIU corresponds to 1 pg/mm² surface coverage of a typical protein. 100-fold improvement using Selectively Amplified Surface Plasmon Resonance. |
Working range | kon = 10E3 < ka < 10E8 M-1 s-1 koff = 0.1 < kd < 10E-7 s-1 KD = 10E-3 - 10E-12 M-1 |
Fastest sampling rate | from 4 ms in Fixed Angle advanced timing mode |
Temperature control | 15-45oC (ambient +20/-7oC) |
Note on working range: Values ka and kd are also dependent of each other, as well as the Bmax (binding maximum) values of the assay at the time, so in principle it is completely sample dependent range and the given ranges are just a guideline.
Extending working range: The range can be extended with careful experimental design. Please refer to J. Mol. Recognit. 2005; 18: 307–317 for more information.
Another option to extend the working range is Selectively Amplified Surface Plasmon Resonance (SAMP-SPR) technology that can be applied with SPR Navi™ instruments having additional wavelength (785 nm). SAMP-SPR is ideally suited to measure low concentrations of analyte in complex biological mixtures, with 100 times increased sensitivity and significantly reduced interference from background non-specific binding. This technology can be used to extend the range of affinity.
