Crystallization Conditions

crystal ID	method	pH	temperature	details
1	VAPOR DIFFUSION, HANGING DROP		298	0.4 M NaCl, 100 mM HEPES pH 7.2, 50 mM beta-mercaptoethanol at 298K (3 ul of 5.5 mg/ml protein plus 1 ul of well buffer in the crystallization drop). The formed crystal was soaked in 30% PEG400, 13mM MgCl2, 33mM NaF, 50 mM beta-mercaptoethanol, 66 mM HEPES, pH 7.2, and 5 mM 5-InsP7 for 2 days, and transferred into pH 10.0, 50 mM CHES for 1 hour.
