SPR instruments

Surface plasmon resonance (SPR) can be used to measure binding events because it is very sensitive to changes in refractive index. SPR instrument are made up of an optical measurement system, a fluid handling system, and a sensor chip.

How does SPR work?

The sensor chip is a gold film coated on a glass substrate that has been chemically modified to make it easier to immobilize one of the binding partners onto the surface of the sensor: the ligand. The molecule in solution is the analyte.

The optical system consists of a light source and a detector. The light source illuminates the gold film, and the detector measures the unique optical spectrum produced by the SPR phenomenon. Most SPR instruments utilize a laser that shines through a prism beneath the sensor chip, generating a total-internal-reflection condition.

The reflected light will have a characteristic dip in intensity at a certain angle due to the plasmonic wave, which is measured with a detector. When a molecule binds to the surface of the sensor chip, the refractive index of the space in which the plasmonic wave is propagating through changes, and the reflectance angle will shift. The amount it shifts depends on how much mass of material has bound to the surface, and the shift can be measured in near real time.

ALTO SPR SYSTEM

Alto is the world’s first SPR instrument to integrate digital microfluidics (DMF) with nanotechnology-based biosensors.

DMF technology enables all fluidics to be disposable, allowing for precise handling of 2µL sample volumes, crude sample compatibility, and zero fluidics maintenance. Alto’s compatibility with automation for both hardware and software provides sample-in/answer-out data, industry-leading throughput, and 24+ hours of unattended run time.

Every aspect of Alto is designed with user-friendliness and accessibility in mind-from the flexible 16 channel design to the intuitive data analysis platform.

Benefits:

Industry leading Data Quality: maximise data quality eliminating sample dispersion and evaporation.
Sample-Friendly: Get full kinetic analysis with only 2μL of crude or purified sample - 100X less than traditional SPR!
Spend 70% less time at the bench: High-Throughput Powered by Automation with no purification, dilutions, tagging, degrassing cleaning or manual assay design required.
User-friendly: label-free platform deisgned for biologics research

GxP Software expansion: The features in the Alto GxP software expansion are specifically designed to support compliance with the FDA’s 21 CFR Part 11 guidelines around electronic records.
