Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	6.5	298	CXrystals were grown by sitting drop in Cryschem plates using 0.6 ml reservoirs of 20% PEG 3350 in 0.1M MES buffer. The drops were 6 ul composed of equal amounts of protein at 30 mg/ml in water with the reservoir solution. Temperature was 298 K and crystals appeared after about two weeks
