    Method VAPOR DIFFUSION, HANGING DROP
    pH 5.5
    Temperature 298.0
    Details The purified ParC55 protein was dialyzed against 20 mM Tris-HCl, pH 7.0, 200 mM NaCl, 10% glycerol, 1 mM beta-mercaptoethanol, 0.05% NaN3 then concentrated to 3-4 mg/ml. Hanging drops were formed by mixing equal volumes of protein and crystallization solutions (100 mM Tris-HCl, pH 5.5, 200 mM NaCl, 1 mM beta-mercaptoethanol, 0.05% NaN3 and 10% of 1:1 ethanol-isopropanol as precipitant). , VAPOR DIFFUSION, HANGING DROP, temperature 298.0K
