1 | VAPOR DIFFUSION, HANGING DROP | 8.5 | 280 | Hanging drop vapor diffusion at 4C, with initial concentration in drop of 0.13 mM DNA, 0.33 mM Hin, 46 mM Tris (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 280K |
