Characterization of binding interactions by isothermal titration calorimetry

Abstract Isothermal titration calorimetry is a high-accuracy method for measuring binding affinities. Titration calorimetry is a universal method that has broad impact throughout biotechnology. In recent years, microcalorimeters that are capable of characterizing binding interactions of biological macromolecules have become commercially available. Results from these studies are providing new insight into the molecular nature of macromolecular interactions.
