Effects of Solution Stirring on Protein Crystal Growth

Effects Of Solution Stirring On Protein Crystal Growth

We report the influence of solution stirring on the growth of hen egg white lysozyme crystals. Solution stirring rate was controlled by varying the rotation speed of a rotary shaker. A range of precipitation agent sodium chloride concentrations was also investigated. The time required for crystal nucleation to occur was observed to be much greater in stirred samples than in unstirred samples.

Tackling Difficult Mixing Problems AIChE

Tackling Difficult Mixing Problems Aiche

Mixing non-Newtonian fluids may be doubly complicated when the mixing process creates the non-Newtonian proper-ties. For example, a formulation process may start with a low-viscosity liquid, and mixing causes the viscosity to increase until the fluid becomes non-Newtonian. Sometimes mixer power may be used as an indicator of final fluid viscosity.
