蛋白质-蛋白质相互作用参与大多数细胞过程的调节和功能。因此,许多努力都旨在开发能够定量蛋白质-蛋白质相互作用的方法,其中无标记方法由于相关的简化工作流程和最小化标记诱导的扰动而特别令人感兴趣。在这里,我们回顾了最近的进展,光学技术提供了无标记的亲和力和动力学的体外测量。我们提供了一个概述和比较现有的技术及其原理,讨论的优点,局限性和最近的应用。蛋白质-蛋白质相互作用参与大多数细胞过程的调节和功能。
Protein–protein interactions are involved in the regulation and function of the majority of cellular processes. As a result, much effort has been aimed at the development of methodologies capable of quantifying protein–protein interactions, with label-free methods being of particular interest due to the associated simplified workflows and minimisation of label-induced perturbations. Here, we review recent advances in optical technologies providing label-free in vitro measurements of affinities and kinetics. We provide an overview and comparison of existing techniques and their principles, discussing advantages, limitations, and recent applications. Protein–protein interactions are involved in the regulation and function of the majority of cellular processes.
