Dear Will, if the crystals grow in vapour-diffusion, you can try to overlay the reservoir with oil to slow down the crystallization process. I know at least two cases where this technique helped to get plate-shaped crystals into more 3D shape.

I have been trying to crystallise a DNA regulator. I got microcrystals in 1.3M Lithium > Sulphate and 50 mM Cacodylate pH = 6. Through a combination of condition refinement and seeding I have attained crystals with a plate-like habit of > dimension 50micron, 50micron, <1micron. These have very weak (8Ã ) anisotropic diffraction at DLS i24 but as theyâre so wafer thin there has been no improvement. Any suggestions to make them more 3D would be great.
