Flight Concentrations Determined

After review of crystals grown so far, Celeste and Josie have selected a 2:1 ratio of lysozyme protein to citrate buffer. This means that in the 125mL of Well A there will be — ml/mg lysozyme protein and === ml citrate buffer (pH 4.0). Well A will also contain a 0.3 x 0.3 square of cotton. In microgravity materials do not mix as they do on earth and it is the hope of the girls that the cotton will act as a wicking agent between Well A and Well B. Well B will contain 12ml NaCl solution.

These materials have been packaged for flight! With each small step the flight experiment is becoming reality!
