Differential Scanning Calorimetry (DSC) is a relatively rapid, straightforward and nonperturbing technique for studying the thermotropic phase behavior of hydrated lipid dispersions & of reconstituted lipid models or biological membranes. However, because of the diversity of lipid thermotropic phase behavior, data-acquisition and data-analysis protocols must be modified according to the nature of the phase transition. The information content of DSC thermograms is affected by the nature of the lipid phase transition. A wide variety of temperature-induced transitions in biological systems may be possible by differential scanning calorimetry (DSC). This includes processes, such as thermal unfolding (denaturation) of proteins, lipid membrane phase transitions, nucleic acid melting & so forth.
