The analysis of biomolecular interactions is key in the drug development process. Label-free biosensor methods provide information on binding, kinetics, concentration, and the affinity of an interaction. These techniques provide real-time monitoring of interactions between an immobilized ligand (such as a receptor) to an analyte in solution without the use of labels. Advances in biosensor design and detection using BioLayer Interferometry (BLI) provide a simple platform that enables label-free monitoring of biomolecular interactions without the use of flow cells. We review the applications of BLI in a wide variety of research and development environments for quantifying antibodies and proteins and measuring kinetics parameters.
