Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 8.5 298 The purified protein was concentrated to 10 mg/mL and with 1 mM SAM. SAM bound protein crystals were obtained by hanging drop vapor diffusion method at 17C using 10% (w/v) ethanol, 5% (w/v) glycerol, 0.1 M tris pH 8.5 as the well solution. A-196 was soaked into the crystals
