1	VAPOR DIFFUSION, SITTING DROP	6.5	293.15	20 mg/ml protein working stock was prepared from 2:1 v/v mixing of 30mg/ml protein in 20mM Tris pH 8, 1mM DTT and 50mM HEPES pH 7.3, 100mM NaCl. Then the working protein stock at 20 mg/ml is mixed at 1:1 v/v ratio with reservoir solution of 0.1M MES pH 6.5, 30% PEG3350, 0.4M MgCl2
