Crystal growth of ribonuclease S under microgravity

Expecting that protein crystal growth in space would show us a new aspect of its crystallization process and might result in the improvement of crystal quality, we performed a series of growth experiments for bovine pancreatic ribonuclease S crystals under microgravity. For this purpose, the COSIMA2 system launched in September 1989 was utilized. In one of the eight crystallization chamber setups in the COSIMA2 experiment, a large "Z-form"...
