Differential Scanning Calorimetry (DSC)

Analytical

Differential Scanning Calorimetry (DSC) — A thermal analysis technique measuring heat flow associated with peptide transitions such as melting, denaturation, and aggregation.

What Is DSC?

Differential scanning calorimetry (DSC) measures the heat absorbed or released by a peptide as temperature is increased, detecting unfolding/melting transitions, aggregation, and phase changes. The melting temperature (Tm) from DSC quantifies peptide thermal stability and is used to rank formulation conditions.

Applications

Tm determination: Higher Tm = more thermally stable. Screen buffers, pH, excipients
Formulation screening: Conditions giving highest Tm are most stabilizing
Glass transition (Tg): DSC measures Tg of lyophilized peptide cakes

Frequently Asked Questions
