1	VAPOR DIFFUSION, SITTING DROP	8	293	Crystals were grown in a MRC SD2 plate set by a STP Labtech Mosquito. Protein at 17.89 mg/ml (390 uM) and 500 uM CA157 were inc for 30 min at ambient temp prior to setting the plate. The droplet providing the crystal used for data collection and refinement was 200 nL of protein-CA157 solution and 25 nL reservoir, 0.65 M sodium succinate pH 7, 0.1M HEPPS buffer, pH 8.0.
