| 1 | VAPOR DIFFUSION, SITTING DROP | 8.5 | 289 | 0.2 ul of 15 mg/ml protein in 20 mM HEPES pH 7.5, 150 mM NaCl, 10% Glycerol, 0.1% Sodium Azide, 0.5 mM TCEP 10 mM NADP and 10 mM glycolic acid were mixed with 0.2 ul of the MCSG-I condition #45 (0.2 M Sodium Chloride, 0.1 M Tris:HCl pH 8.5, 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 was incubated with 1/50 v/v of 2 mg/ml TEV solution at 289 K. |
