1	VAPOR DIFFUSION, SITTING DROP	8	291	Purified ADAM-8/batimastat complex (10mg/mL) was crystallized by the sitting-drop vapor diffusion method, mixing 1uL complex with 1uL of 0.1M Tris pH 8.0, 1M sodium formate, 10% methanol. Crystals reached usable size in 10 days. Crystals were then transferred to a cryo solution containing 0.1M Tris pH 8.0, 1.2M sodium formate, 10% methanol, and 10% glycerol. The crystals were harvested and flash frozen in liquid nitrogen for data collection., VAPOR DIFFUSION, SITTING DROP, temperature 291K
