Abstract

Microscale thermophoresis (MST) is an emerging technology for studying a broad range of biomolecular interactions with a high sensitivity. The affinity constant can be obtained for a wide range of molecules within minutes based on reactions in microliters. Here we describe the application of MST in quantifying protein-carbohydrate interactions. A CBM3a and a CBM4 are titrated with insoluble substrate (cellulose nanocrystal) and soluble oligosaccharide (xylohexaose), respectively.
