Application Notes:
Differential Scanning Calorimetry (DSC) measures the heat changes that occur during controlled increase (or decrease) in temperature.
A
biomolecule in solution is in equilibrium between the native (folded) and its
denatured (unfolded) state. The higher the transition midpoint (Tm) when 50% of
the biomolecules are unfolded, the more stable the molecule. DSC is also used
to determine the change in heat capacity (
Cp) of
denaturation.
DSC can elucidate the factors that contribute to the folding and stability of native biomolecules, including hydrophobic interactions, hydrogen bonding, conformational entropy, and the physical environment.
