Protein crystallization - Wikipedia
Protein crystallization is the process of formation of a regular array of individual protein molecules stabilized by crystal contacts. If the crystal is sufficiently ordered, it will diffract . Some proteins naturally form crystalline arrays, like aquaporin in the lens of the eye.

Protein Crystallization for X-ray Crystallography - PMC
Introducing the sample to precipitating agent can promote the nucleation of protein crystals in the solution, which can result in large three-dimensional crystals growing from the solution. There are two main techniques to obtain crystals: vapor diffusion and batch crystallization.
Introduction to Protein Crystallization, Crystallization Methods
Protein crystallization starts from protein production (cloning, expression & purification) and subsequent thorough characterization of the purified protein in solution. For crystallization, the protein should be of high purity (better than 99%), stable and monodisperse.
