A Comparative Study of Impurity Effects on Protein Crystallization: Diffusive versus Convective Crystal Growth

The incorporation of impurities during protein crystallization is one of the main obstacles that prevents the growth of high quality crystals. Mass transport has been shown to affect the incorporation of impurities. Here we used a special growth configuration that enables the simultaneous investigation of the two main means of mass transport, diffusion and convection, under otherwise identical conditions. Two polymorphic forms of hen egg-white...
