摘要: 微量热泳动(MST)技术是近年来兴起的一项用于研究生物分子间互作的新技术。其检测是基于热泳动现象,即分子在温度梯度中的定向运动及由此引起分子性质的变化,如分子大小、电荷和水化层及构象等。该方法把精确的荧光检测与灵敏的热泳动相结合,从而提供了一个灵敏的、快速的精确分析生物分子间互作的检测方法。就MST的工作原理和检测过程及其在生物学研究中的应用作以综述。

Abstract: Microscale Thermophoresis(MST)is a new technique to study biomolecular interactions in recent years. It is based on thermophoresis, i.e., the directional movements of molecules in a temperature gradient, which results in subsequent changes of molecular properties such as sizes, charges, hydration shell and conformation. MST combines the precise fluorescence detection and sensitive thermophoresis and provides a sensitive, fast and precise detection technique to analyze biomolecular interactions. Wor­king principle, detection process and application of MST in biology researches are reviewed here.

Key words: microscale thermophoresis, interaction analysis, binding studies, biomolecular interaction
