1 | VAPOR DIFFUSION, HANGING DROP | 7.5 | 293 | The purified protein solution, concentrated to about 20 mg/ml in 50 mM Tris-HCl (pH7.5), was incubated in the presence of the inhibitor in 12% (w/v) PEG 4000, 0.5 M magnesium acetate, and 0.1 M Tris-HCl (pH 7.0) for five days by the hanging-drop vapor diffusion method at 293 K. The inhibitor at final concentrations were 0.5 mM., VAPOR DIFFUSION, HANGING DROP |
