1VAPOR DIFFUSION, SITTING DROP5293200 nL of a solution containing 59 mg/mL protein, 50 nM NaCl, 5 mM MOPS buffer pH 7 was mixed with 130 nL reservoir solution containing 16% PEG3350, 0.2 M MgCl2, and 0.1 M sodium acetate buffer at pH 5. Vapor diffusion in MRC plates. Crystals appeared within a few days, and were cryo-protected using a reservoir solution supplemented to 35% PEG3350.
