Webb23 feb. 2016 · DSC provides a relative measure of the thermal stability of a folded protein, which typically changes upon its interaction with a stabilizing partner such as a ligand, another protein, or a membrane. 26,27 As solvent channels are restricted and proteins become more compact, the T m typically shifts to higher temperatures. WebbThe stabilization of proteins against thermal denaturation, and the inﬂuence of small molecules, can also be measured by differential scanning calorimetry (DSC) ordifferential scanning light scattering (DSLS). DSC in an automated version (capDSC, MicroCal, LLC13) allows a series of up to 192 protein/compound combinations.

Webbconformational stability (i.e., the ability to retain their native secondary, tertiary, and quaternary structures).1,2 Conformational stability can be assessed by measuring thermal stability with the use of techniques sensitive to changes in protein folding, such as circular dichroism, fluo-rescence spectroscopy, light scattering, DSC, and DSF. A WebbDSC is a biophysical characterization technique used to study the stability of compounds including lipids, proteins, and oligonucleotides, in their native state. This type of measurement is of interest for antibodies because stability directly impacts their structure and ultimately their function [2-3]. This stability is often reported as T m remind function slack
