The MicroCal VP-ITC is a powerful and sensitive, easy-to-use isothermal titration calorimeter that offers the ability to investigate any biomolecular interactions. This fast, convenient, label free and in-solution technique 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.
The MicroCal VP-ITC delivers affinity data that provide insight into biomolecular interactions and can be used to investigate any such interaction. Isothermal Titration Calorimetry is label free, and in solution, and is fast, convenient and offers a free choice of buffers and no limitations with respect to molecular weight.
The MicroCal VP-ITC is complete system that requires no additional accessories, reagents or consumables. Once the samples are loaded it operates unattended, freeing the user for other tasks.
Isothermal Titration Calorimetry (ITC) measures the binding affinity and thermodynamics between any two biomolecules. When substances bind, heat is either released or absorbed. Measurement of this heat change in an ITC experiment enables accurate determination of binding constants (KD), interaction stoichiometry (n), enthalpy (ΔH) and entropy (ΔS), providing a complete thermodynamic profile of the molecular interaction in a single experiment.
MicroCal VP-ITC can also be used to determine heat capacity changes upon binding by performing experiments over a range of temperatures.
