ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	6.5	295	Crystals grown by sitting drop with 0.6 ul reservoirs of 20% PEG 3350 in 0.1 M MES buffer at pH 6.5. Drops of 8 ul composed of equal amounts of the protein at 30.0 mg/ml in water with the reservoir solution. Room temperature throughout, crystals grew in about a month
