1	VAPOR DIFFUSION, SITTING DROP	5.5	289	0.2 ul of 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 Hampton Index HT #65 (F5) (0.1 M Ammonium acetate, 0.1 M BIS_TRIS pH 5.5, 17% (w/v) Polyethylene glycol 10,000) and equilibrated against 1.25 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 solution at 289 K for 3 hours.
