WebSep 20, 2024 · To achieve that fit, scientists need detailed knowledge of the structure of both proteins, and one of the best ways to analyze a protein structure is to grow it in crystalline form. During the Space Shuttle and Mir programs, researchers discovered that they could produce higher quality protein crystals in microgravity than on Earth. In the process of protein crystallization, proteins are dissolved in an aqueous environment and sample solution until they reach the supersaturated state. Different methods are used to reach that state such as vapor diffusion, microbatch, microdialysis, and free-interface diffusion.
