Kinetic analysis of biomolecular interactions is critical during drug discovery and development. The affinity of an interaction directly affects the dose required for a biopharmaceutical to be effective. Real-time data on affinity and the kinetics of binding can provide useful information at every stage of biopharmaceutical reagent development.

Potency assays can be used throughout the development process in comparability and formulation studies and are required for release of every lot of therapeutic protein.
