The assay readout is a profile of protein–dye complex fluorescence intensity as a function of temperature.

WebAmong biopolymers, proteins are unique in displaying useful intrinsic fluorescence. Lipids, membranes, and saccharides are essentially nonflu-orescent, and the intrinsic fluorescence of DNA is too weak to be useful. In proteins, the three aromatic amino acids— phenylalanine, tyrosine, and tryptophan—are all fluorescent.
