Differential Scanning Fluorimetry (DSF) measures protein unfolding by monitory changes in fluorescence as a function of temperature.
Conventional DSF uses a hydrophobic fluorescent dye that binds to proteins as they unfold.
NanoDSF measures changes in intrinsic protein fluorescence as proteins unfold.
Prometheus characterizes thermal stability of protein samples...
…absolutely label-free, measures the intrinsic fluorescence of a protein while it’s being subjected to thermal denaturation.
Only microliters of sample are required, at extremely low concentrations.
Good at screening buffer influences or testing formulation and storage conditions.
