Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	8.5	281	Hanging drop vapor diffusion at 4C, with initial concentration in drop of 0.13 mM DNA, 0.33 mM Hin, 46 mMTris (pH 8.5), 46 mM CaCl2, 63 mM NaCl, 11.6% v/v PEG400, and 2.03 mM Na cacodylate. Reservoir solution contains 100 mM Tris (pH 8.5), 100 mM CaCl2, 100 mM NaCl, and 25% PEG400. Concentration of PEG400 in reservoir solution was increased in 5% increments to 35%., VAPOR DIFFUSION, HANGING DROP, temperature 281K
