1VAPOR DIFFUSION, SITTING DROP8.5289FruK (3.4 mg/mL) in 20 mM MOPS/KOH buffer (pH 7.4) containing 75 mM KCl and 1 M L-proline was mixed in a 1:1 ratio with condition containing 1 M ammonium sulfate, 75 mM TRIS/HCl (pH 8.5), 150 mM lithium sulfate, 2 mM fructose-1-phosphate, 4 mM ADP, and 10 mM magnesium chloride. The final drop volume was 0.8 microliters. Before plunge freezing the crystals in liquid nitrogen, glycerol was added to the drop as a cryo-protectant to a final concentration of 35% (v/v).
