The MicroCal VP-ITC is a powerful and sensitive, easy-to-use isothermal titration calorimeter that offers the ability to investigate any biomolecular interaction. Its fast, convenient label-free in solution analysis delivers the information needed to characterize the molecular interactions of proteins, antibodies, nucleic acids and other biomolecules. The system is widely used in research environments for lead optimization, hit validation, assessing the driving mechanisms of binding and studying enzyme kinetics and inhibitor design.
