MicroScale Thermophoresis (MST) quantifies biomolecular interactions rapidly. This study applied MST to measure binding affinities for two carbohydrate-binding modules (CBMs) interacting with cellulose and xylohexaose.

Area of Science:

  • Biochemistry
  • Biophysics
  • Materials Science

Background:

  • MicroScale Thermophoresis (MST) is a sensitive technique for analyzing biomolecular interactions.
  • It enables rapid determination of binding affinities using minimal sample volumes.

Purpose of the Study:

  • To demonstrate the utility of MST for quantifying carbohydrate-binding module (CBM) interactions.
  • To measure the binding affinity of CBM3a to cellulose nanocrystals.
  • To measure the binding affinity of CBM4 to xylohexaose.

Main Methods:

  • Utilized MicroScale Thermophoresis (MST) to analyze molecular binding.
  • Quantified interactions between CBM3a and cellulose nanocrystals.
  • Quantified interactions between CBM4 and xylohexaose.
