Microgravity

The Protein Crystallization for Microgravity (DCAM) was developed at NASA's Marshall Space Flight Center. A droplet of solution with protein molecules dissolved in it is isolated in the center of a small well. In orbit, an elastomer seal is lifted so the solution can evaporate and be absorbed by a wick material. This raises the concentration of the solution, thus prompting protein molecules in the solution to form crystals. The principal investigator is Dr. Dan Carter of New Century Pharmaceuticals in Huntsville, AL.
