The flight video pictures showed the apparition of the first crystals. The photographs before and after transport showed no significant difference. The dialysis technique proved to be suitable since no additional nucleation was generated by the membrane. The dialysis membrane confines the protein in its chamber, whereas in the FID technique protein diffuses towards the reservoir, especially in the case of small proteins, long duration missions, and occurrence of shocks originating from on board activities during the mission. No significant shift of the nucleation zone was observed with lysozyme when comparing data of space and ground grown crystals.
Data vary with the crystallisation set-up.
These values being a combination of sample mosaicity along with instrument smearing should be taken on a qualitative basis. Alternative methods for characterising the mosaicity of crystals have since been developed.
