Characterization of Cationic Vector-Based Gene Delivery Vehicles Using Isothermal Titration and Diff

Within the past 10 years, major advances in the design and development of differential scanning calorimeters (DSC) (1 ) and isothermal titration calorimeters (ITC) (2 ) have resulted in an unparalleled level of sensitivity, stability, and reproducibility in calorimetric measurements of large molecules. These improvements have allowed the thermal stability and ligand binding processes of biological macromolecules to be thermodynamically characterized with speed, accuracy, and convenience. With their increasing commercial availability, experiments that were previously limited to specialist calorimetry laboratories can now be routinely performed by most investigators.
