Thermophoretic coefficient

MST is based on the quantifiable detection of a fluorescence change in a sample when a temperature change is applied. The fluorescence of a target molecule can be extrinsic or intrinsic (aromatic amino acids) and is altered in temperature gradients due to two distinct effects. On the one hand temperature related intensity change (TRIC), which describes the intrinsic property of fluorophores to change their fluorescence intensity as a function of temperature. The extent of th… Webbis called Soret coefficient. The thermophoresis factor has been calculated from molecular interaction potentials derived from known molecular models . Applications. The …
