1VAPOR DIFFUSION, SITTING DROP8.5289.150.3 uL 16.32 mg/mL FphA (10 mM Tris-HCl PH 8.0, 10 mM NaCl) were mixed with 0.15 uL of reservoir solution. Sitting drop reservoir contained 25 uL 0.1 M Tris pH 8.5 and 0.7 M Sodium citrate tribasic dihydrate. Crystal appeared after 35 days at 16C and grew larger for another month when it was frozen in a solution of ~25% glycerol, 75% reservoir.
