Isothermal titration calorimetry (ITC) is widely used to detect the affinity and enthalpy of interactions between proteins and/or other molecules. In addition, the quantitative nature of ITC is useful in the characterization of recombinant proteins, as well as to determine the ratio of proteins capable of binding specific ligands, thus determining protein purity. Creative Biostructure rapidly integrates expertise and related businesses, providing high-quality ITC services for applications such as biomolecular interactions involved in coronavirus infection research.
