Bio-Layer Interferometry (BLI) is another label-free technology that measures molecular interactions in real time for the purpose of detection, quantitation and kinetic analysis. Target molecules bind to the coated surface of the fiber-optic biosensors, forming a molecular layer that changes the spectral pattern of the reflected light. This technology is useful for basic research in protein-ligand interaction and for applications in biotherapeutic drug discovery and development. The facility is equipped with one advanced BLI instrument:
Octet Red 384 (ForteBio)
Octet Red 384 has measurement capacities ranging from 102-107 M-1s-1 for the association rate and 10-6-10-1 s-1 for the dissociation rate. The affinity constant KD ranges from 1mM to 10 pM. A number of specific biosensors are available from the manufacture.
