1 | VAPOR DIFFUSION, SITTING DROP | 289 | 0.2 ul of 12 mg/ml protein in 20 mM HEPES pH 7.5, 150 mM NaCl, 10% Glycerol, 0.1% Sodium Azide, 0.5 mM TCEP, and 5 mM NADP were mixed with 0.2 ul of the MCSG-I condition #6 (0.2 M Ammonium Sulfate 0.1 M Bis-Tris:HCl pH 5.5 25% (w/v) PEG 3350) and equilibrated against 1.5 M NaCl solution in 96 Well 3 drop Crystallization Plate (Swissci). Before crystallization, the protein-ligand mixture was incubated with 1/40 v/v of 2 mg/ml chymotrypsin solution at 289 K for 3 hours |
