粒子与混合势相互作用的相分离和动力学捕获--再论球状蛋白质的情况
Phase separation and dynamical arrest for particles interacting with mixed potentials--the case of globular proteins revisited
摘要：
我们研究了扩展的对应态定律（ELCS）的适用性，平衡和非平衡的球形蛋白质溶菌酶的状态图的功能。我们提供了令人信服的证据表明，ELCS正确地再现了不同离子强度的双节点的位置，但未能描述逮捕线的位置。随后，我们使用模式耦合理论（MCT），以获得更多的了解这些意见的起源。我们证明，而临界点和连接的双结点和旋结点的规范化的第二维里系数所描述的相互作用势的积分功能，逮捕线主要是由有吸引力的井深或键强度。本文发表在《软物质》上。参考：DOI：10.1039/c 0 sm 01175 d
英文摘要：
We examine the applicability of the extended law of corresponding states (ELCS) to equilibrium and non equilibrium features of the state diagram of the globular protein lysozyme. We provide compelling evidence that the ELCS correctly reproduces the location of the binodal for different ionic strengths, but fails in describing the location of the arrest line. We subsequently use Mode Coupling Theory (MCT) to gain additional insight into the origin of these observations. We demonstrate that while the critical point and the connected binodal and spinodal are governed by the integral features of the interaction potential described by the normalized second virial coefficient, the arrest line is mainly determined by the attractive well depth or bond strength.
