Pressure perturbation calorimetry (PPC) is a new technique that makes possible to study the volumetric changes that occur upon protein unfolding. Here, we summarize the thermodynamic foundation of the method and introduce a two-state model for the analysis of the unfolding data monitored by PPC. Several examples of data analysis illustrating potential pitfalls and solutions are discussed.
压力扰动量热法(PPC)是一种新技术,它能够研究蛋白质展开过程中发生的体积变化。在此,我们总结该方法的热力学基础,并介绍一种用于分析由PPC监测的展开数据的双态模型。讨论了几个说明潜在陷阱和解决方案的数据分析示例。
