1VAPOR DIFFUSION, SITTING DROP281concentrated CA II at ~10 mg/mL was set up in SD-2 plates (Molecular Dimensions) with the following ratio of protein plus reservoir plus seeds: 250 nL + 225 nL + 25 nL. The plate was incubated at 8 C and the reservoir condition consisted of 2.9 M ammonium sulfate with 0.1 M Tris buffer at pH 8.3. Dry compound was added to the crystallization drop after crystals had formed and several days before data were collected.
