Objectives
Use of GCB in space
  • The tasks performed in the framework of this
    project were
  • The design and construction of a passive
    apparatus (Granada Crystallisation Facility, GCF)
    to perform counter-diffusion experiments in the
    ISS inside capillaries using the Granada
    Crystallisation Box (GCB).
  • To perform preliminary experiments to tune the
    optimal crystallisation conditions for a wide set
    of proteins.
  • To analyse the results of the experiments related
    to the crystallisation environment and kinetics,
    and to compare them with those of numerical
    simulations of fluid dynamics.
  • To collect the X-ray diffraction data and to
    compare the results with those of identical
    experiments carried out on Earth To be carried
    out by the owner of the macromolecule.

Results
Use of GCB in space
GCB Validation as a Flight Facility
  • None of the GCBs suffered any damage
  • All the capillaries remained in position
  • None of the gels were broken
  • No leakage occured that could affect the
    physicochemical conditions of the experiment
  • When there were no crystals from space there
    were none in the on-ground experiment, either,
    and vice versa

Conclusions
Use of GCB in space
Conclusions
  • The results validate the GCB for space
    experiments as a passive, inexpensive and
    high-density crystallisation facility for growing
    protein crystals.
  • The crystals grown with the counter-diffusion
    technique share excellent global indicators of
    X-ray quality.
  • From the point of view of structural resolution,
    there are no obvious differences between crystals
    grown under reduced convective flow in space and
    crystals grown under convection free conditions
    on ground.

Would crystals grown from ungelled solutions in
the steady diffusion regime yield better X-ray
diffraction data sets?
How the unsteady diffusion-convection regime
affects the pattern formation in
counter-diffusion experiments?
How do gels affect the quality of the crystals
depending on concentration and type of gels?
Which is the best X-ray data acquisition protocol
for comparative studies?
