Calorimetry
Calorimetry — The measurement of heat changes during chemical or physical processes, applied to peptide research through DSC and ITC to study folding and binding thermodynamics.
What Is Calorimetry?
Calorimetry measures heat changes in chemical and biological processes. In peptide research, isothermal titration calorimetry (ITC) directly measures binding thermodynamics, while differential scanning calorimetry (DSC) measures thermal stability and unfolding transitions. Both are label-free biophysical methods that provide thermodynamic parameters unavailable from other techniques.
Calorimetric Methods
- ITC: Measures ΔH, Kd, n, ΔS of peptide-target binding in solution
- DSC: Determines peptide melting temperature (Tm) and unfolding enthalpy (ΔHcal)
- DSC for formulation: Compare Tm in different buffers and excipients to optimize peptide stability
