Biolayer interferometry explained
WebNational Center for Biotechnology Information 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…
