1VAPOR DIFFUSION, HANGING DROP8293Holo protein at 10 mg/mL in 10 mM Tris pH 7, 100 mM NaCl, 2.5 mM 2-mercaptoethanol was mixed with 0.1 M bis-tris propane pH 8.0, 0.1 M MgCl2, 20% (w/v) PEG 3350 and a crystal seed stock in a 0.75:1.0:0.25 (v/v) ratio. The seed stock was prepared in the same crystallization buffer. Suitable crystals were cryo-protected in an equilvalent precipitant solution supplemented with 22% (v/v) ethylene glycol.
