Dr. Larry DeLucas joined The Space Show guest family for this program to discuss protein crystallization in microgravity. Dr. DeLucas explained the basics to us, we spoke at length about both pharmaceutical and commercial interest and applications. We discussed space access and its costs in terms of doing something commercial in space regarding protein crystal growth. Dr. DeLucas explained the success ratio, compared it to growing proteins on Earth, talked about the need for a gentle re-entry and what that means, why the g-force will damage the proteins, and much more.
