Characterizing protein-protein interactions by ITC
9 Mar 2026Understanding protein–protein interactions is essential for revealing biological mechanisms, yet many analytical methods struggle to deliver direct, quantitative thermodynamic data. Explore how isothermal titration calorimetry (ITC) overcomes that challenge by providing a label‑free, solution‑based approach to measure binding affinity, stoichiometry, and energetics in a single experiment. Plus, learn how ITC streamlines characterization workflows, improves data confidence, and supports more informed decision‑making in protein research.

ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.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.isothermal titration calorimetryProtein InteractionsProtein interactions are essential for understanding cellular processes, as proteins work together to carry out biological functions.
