Influence of gravity on post-nucleation transport in liquid/liquid diffusion chamber of protein crystallization

摘要

Based on a space experiment of lysozyme crystallization, a two-dimensional model was designed to study numerically the post-nucleation transport in the liquid/liquid diffusion crystallization of proteins. The initial concentration distributions for protein and salt were calculated with a purely diffusive process before nucleation. The results of simulation show that a noticeable depletion zone of protein also exists around a growing crystal in liquid/liquid diffusion chamber under og condition.
