Our idea
  • Wanted to help friend Brittany
  • Looked at cancer research projects
  • Chose Urokinase protein crystal growth

3
Hypothesis
  • We think the Lysozyme crystals will grow
    better and there will be more crystals in
    microgravity than when they are grown on Earth.
    We think this because gravity will affect the
    ionic bonds, making them weaker. In microgravity
    however, the bonds should be stronger, therefore
    giving us better results.

4
Experimental Design
  • 21 of protein to NaCl
  • Lysozyme
  • NaCl 5
  • A 3 mm by 3 mm piece of cotton in a few of the
    wells.

5
Experiment Conditions
  • Ground truth experiment
  • Residential home
  • Lab conditions
  • Space shuttle
  • Microgravity

6
Problems/Solutions
  • Urokinase
  • New enzyme
  • Shuttle delay
  • Transportation
  • Diffraction lab

7
Results
  • Controlled environmentcrystals.
  • Didnt find crystals in the space
  • shuttle or home ground truth samples,
  • because they were kept in uncontrollable
  • environments.
  • Crystals found in the lab ground truth,
  • because the lab has a stable
  • environment.

8
Conclusion
  • Lab conditions need to be constant
  • Shipping crystals should have been frozen
  • Hypothesis Unsure due to issues with experiment
    conditions
