1VAPOR DIFFUSION, HANGING DROP6.5293.151:1 4.9 mg/mL protein in 150 mM potassium chloride, 20 mM Tris, pH 8.0 + Morpheus II-FX96 (Molecular Dimensions) condition H2 - 40 mM polyamines (spermine tetrahydrochloride, spermidine trihydrochloride, 1,4-diaminobutane dihydrochloride, DL-ornithine monohydrochloride), 50% v/v Precipitant Mix 6 (25% w/v PEG4000, 40% w/v 1,2,6-hexanetriol), 0.1 M Buffer System 4 (Gly-Gly, AMPD) at pH 6.5. The drop was suspended over a 1.5 M ammonium sulfate dehydrating solution and incubated at 20 degrees C for about 5 months.
