Surface plasmon resonance (SPR) is an optical effect that can be utilized to measure the binding of molecules in real-time without the use of labels. SPR instruments are primarily used to measure the binding kinetics and affinity of molecular interactions. 

OpenSPR is a next generation surface plasmon resonance solution that is easy-to-use, cost effective and low maintenance. It is designed for the individual researcher. With our surface plasmon resonance solution, in just minutes you can get affinity, kinetics and specificity for proteins, peptides, antibodies, DNA, RNA, and small molecules.

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 120 hours of unattended run time.
