Applied assay technologies comprise surface plasmon resonance (SPR), e.g. from Biacore TM /Cytiva (formerly GE Healthcare), bio-layer interferometry (BLI), e.g. from FortéBio/Sartorius, and switchSENSE ® from Dynamic Biosensors. Surface plasmon resonance (SPR) can be used to analyze both binding affinities and kinetic parameters between a ligand and an analyte. SPR can be performed by either cross-linking a given ligand to a sensor chip covalently or utilizing high-affinity non-covalent interactions to secure a ligand in a particular conformation to a chip, both of which have their potential advantages.
