TA Instruments – Isothermal Titration Calorimeters
Isothermal titration calorimetry (ITC) is a high-resolution method for complete characterization of the basic chemical details of a binding interaction. The method determines a binding constant, reaction stoichiometry, and total reaction energy of two or more compounds (small or large molecules) in solution. Isothermal titration calorimeters do this by measuring the heat that is released or absorbed when molecules interact with each other.

Temperature conditions can be controlled to understand the temperature dependence of binding.
