1VAPOR DIFFUSION, HANGING DROP8.8293The inhibited ananain was desalted using a PD10 column equilibrated with 20 mM Tris, pH 8.0, 20 mM NaCl and then concentrated to 6.5 mg/ml. A reservoir solution comprised of 72% (w/v) MPD, 0.1 M Tris, pH 8.8. Equal reservoir to protein ratio with streak seeding using previous native ananain crystals
