Sparse matrices for the crystallization of biological macromolecules. Every formulation will flash-freeze to a clear amorphous glass in liquid nitrogen or in the cryo-stream at 100K. Eleven different cryocrystallants and sparing use of glycerol ensures a broad sampling of possible cryo conditions. Crystals can be frozen directly from their growth chambers, thus avoiding the additional step of pre-equilibration with an artificial cryo-solvent that can damage the crystal.

Cryo™ I and II: 10ml each prepared with ultra-pure chemicals and water (18.2 Megohm-cm) followed by sterile 0.22 micron filtration into sterile 15 ml tubes. Include 2 ml each of a Light Silicone Oil (DC-200 BDH#630024N) and a Heavy Parafin Oil (Fluka #76235) for use in modulating vapor diffusion rates. US PATENT 6,267,935.
