TABLE I.
Overview of the advantages and disadvantages of the different thermal unfolding methods applied in drug discovery.
| Technique | Advantages | Disadvantages |
|---|---|---|
| DSC | No dyes, labels, Abs required. Direct measurement of heat capacity and enthalpy of unfolding | High protein consumption, low throughput. |
| DSF | High throughput, lower sample consumption. Can be automated | Requires dye binding. Potential issues with dye binding perturbing the equilibrium. Temperature dependence of fluorescence signal. May detect aggregation of dye. |
| nanoDSF | No dye required. Ability to take the ratio of 2 wavelengths to remove temperature dependence of fluorescence effect | Requires tryptophan / tyrosine content. More sensitive to compound fluorescence. |
| CETSA | Measurement in a physiological setting. A range of detection methodologies available | Complexity of interpretation. |
