Malvern Instruments: The Theory and Practice Behind Isothermal Titration Calorimetry
4 Aug 2015Isothermal titration calorimetry (ITC) is an analytical technique that has become the “gold standard” for studying intermolecular interactions. As its name indicates, it is a titrimetric technique, that is, a volumetric laboratory method for quantitative chemical analysis (traditionally intended to determine the unknown concentration of an identified analyte) where a reagent solution, the titrant, is made to react with a solution of analyte or titrand. This white paper details the use of ITC in biophysical studies.

CalorimetryCalorimetry is a technique used to determine the heat released or absorbed in a chemical reaction. Calorimeters can be categorized into bomb calorimeters, constant pressure calorimeters, differential scanning calorimeters, isothermal titration calorimeters, X-ray microcalorimeters, heat-loss calorimeters, and high-energy particle calorimeters. The choice of calorimeter depends on the application.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.Molecular BiologyMolecular biology is the branch of biology that focuses on the molecular mechanisms that underlie cellular functions.
