1 | VAPOR DIFFUSION, SITTING DROP | 293 | 5 mmol/L compound and 6 mmol/L MgCl2 were added to MTH1. Sitting drop vapor diffusion experiments at 293K were performed, and MTH1 (9.34 mg/mL) was mixed with reservoir solution (32% (w/v) PEG3350, 0.1 mol/L Sodium Acetate pH 4.0 and 0.2 mol/L LiSO4) in a 1:1 ratio. |
