Microgravity
Crystals grown in the hand-held Protein Crystallization Apparatus for Microgravity (PCAM) onboard STS-61C. The PCAM has a pedestal in the center of a circular chamber, the surrounding chamber holds an absorbent reservoir that contains a solution of the precipitant. Vapor pressure differences between the protein solution and the reservoir solution force water to move from the protein solution to the reservoir. As protein concentrations increase, protein crystals begin to nucleate and grow.
