Crystallogenesis studies in microgravity with the Advanced Protein Crystallization Facility on SpaceHab-01

The Advanced Protein Crystallization Facility (APCF), a new protein crystallization device developed by ESA for the IML-2 Mission in 1994, was tested in its maiden flight on STS-57 Mission in SpaceHab-01 with a physico-chemical experiment on lysozyme crystallization. In pre-flight ground experiments, prior to the Shuttle Mission, the protocol for lysozyme crystallization with NaCl was based on its solubility diagram at 18°C and pH 4.5....
