1	VAPOR DIFFUSION, HANGING DROP			4 uL protein solution mixed with 4 uL (0.75-1.00) M NaCl, 0.1 M MES, 0.1 M Na/K PO4, pH 5.6-6.2, suspended over 1 mL reservoir solutions of (1.25-1.50) M NaCl, 0.1 M MES, 0.1 M Na/K PO4, 5 mM beta-mercaptoethanol, pH 5.6-6.2. The trays were set at 4C for 5-7 days to control nucleation, followed by incubation for 3 weeks at 12C to maximize crystal growth, VAPOR DIFFUSION, HANGING DROP
