Understanding biomolecular interactions INTRODUCTION TO ISOTHERMAL TITRATION MICROCALORIMETRY Isothermal titration microcalorimetry (ITC) measures the binding affinity and thermodynamics of biomolecular interactions, helping to understand why interactions occur. The technique is based on the measurement of heat evolved or absorbed when complexes are formed between molecules. It has the advantage of measuring all binding parameters in a single label-free, in-solution experiment, including binding affinity (K D), reaction stoichiometry (n), enthalpy (ΔH), and entropy (ΔS). This reveals thermodynamic...

Understanding biomolecular interactions THE POWER OF ITC Isothermal titration calorimetry determines thermodynamic properties that tell you why interactions occur. Thermodynamic data reveal the forces that drive complex formation to describe function and mechanism at a molecular level. A. ITC determines thermodynamic properties including: the stoichiometry of Unfavorable the interaction (n), the affinity constant (K D), change in enthalpy (ΔH), and change in entropy (ΔS). G B. Shown are thermodynamic signatures of three interactions that have the same binding energy (ΔG). The binding energy is...

Understanding biomolecular interactions Optimizing enzyme kinetics with ITC The kinetics of xylanase is important in bio-bleaching wood pulp and biofuel production. Baumann and coworkers developed a system to measure xylanase kinetics with ITC since the traditional method was complicated and prone to systematic errors. The ITC method was also found to offer greater sensitivity and used less material. Typically, heat changes associated with xylan hydrolysis are too small to measure directly with ITC. To boost heat flow, an enthalpy amplification system that involved carbohydrate oxidase and catalase...
