Isothermal Titration Calorimetry: A Biophysical Method to Characterize the Interaction between Label-free Biomolecules in Solution.


ABSTRACT: This protocol can be applied to analyze the direct interaction between a soluble protein and a target ligand molecule using Isothermal Titration Calorimetry (ITC, Malvern). ITC allows the biophysical characterization of binding between label-free, non-immobilized and in-solution biomolecules by providing the stoichiometry of the interaction, the equilibrium binding constants and the thermodynamic parameters. ITC monitors heat changes (released and/or absorbed) caused by macromolecular interactions with no restrictions of buffer and molecular weight of the macromolecules.
