1	VAPOR DIFFUSION, SITTING DROP	7.5	289	0.2 ul of 10.5 mg/ml protein in 20 mM HEPES pH 7.5, 150 mM NaCl, 10% Glycerol, 0.1% Sodium Azide and 0.5 mM TCEP were mixed with 0.2 ul of the MCSG Suite 2 condition # 23 (0.1M Bis-Tris, 25%w/v PEG 3350, 0.2M Li sulfate pH=6.5 ) and equilibrated against 1.5 M NaCl solution in 96 Well 3 drop Crystallization Plate (Swissci). Before crystallization protein was incubated with 1/50 v/v of 2 mg/ml chymotrypsin and 10 mM NADP solution at 289 K for 3 hours.
