Bio-layer interferometry measures kinetics and biomolecular interactions on a basis of wave interference. To prepare for BLI analysis between two unique biomolecules, the ligand is first immobilized onto a bio compatible biosensor while the analyte is in solution. Shortly after this, the biosensor tip is dipped into the solution and the target molecule will begin to associate with the analyte, producing a layer on top of the biosensor tip. This creates two separate surfaces: the s… WebBLI is an optical technique that analyzes the interference pattern of white light reflected from two surfaces: a layer of immobilized protein on a biosensor tip, and an internal …
